Pregnancy is a beautiful journey of 9 months. There are a lot of changes that occur inside your body in these months. In this article we will explore every aspect of pregnancy and try to clarify every possible doubt regarding pregnancy.

How pregnancy happens?

The average length of menstrual cycle is about 28 days. However, a normal menstrual cycle may be as short as 21 days or as long as 35 days. In every menstrual cycle, ovulation (release of egg/ovum from ovary) occurs about 14 days prior to the beginning of next menstrual period, regardless of the length of menstrual cycle.

Pregnancy happens when the ovum released from your ovary get fertilized by a sperm. Fertilization takes place in the fallopian tube (ampulla region) leading to formation of Zygote.  Within 8-10 days, fertilized egg reaches the uterus and get implanted. If the implantation is successful, it results in pregnancy.

The growth period is classified as:

A) 0-14 days – Ovum

B) 14 days to 9 weeks – Embryo

C) 9th week till birth- Foetus

Trimesters of pregnancy?

The total duration of pregnancy is about 9 months or 280 days or 40 weeks from LMP/last menstrual period. The whole duration of pregnancy is divided into 3 trimesters of approximately 3 months each. It can be interpreted as:

1) First trimester - It includes the first 12 weeks of pregnancy. During this period the foetus grows rapidly. 1st trimester is very crucial period as there are high chances of miscarriage or congenital malformations due to maternal diseases like uncontrolled diabetes or due to drug toxicity.

USG scans plays a vital role specially in early pregnancy - Your obstetrician will order an Ultrasound scan in 1st trimester of pregnancy for the following purpose:

1) To confirm pregnancy

2) To evaluate gestational age of baby

3) To check fetal heart rate

4) To evaluate expected date of delivery (EDD)

5) To check for abnormal implantation such as ectopic pregnancy

6) Multiple pregnancy such as twins, triplets etc.

7) To know the type of gestation, chorionicity and amnionicity

8) To identify causes of abnormal bleeding in initial pregnancy

9)  Abortions/Miscarriage

10) Follow up after miscarriage or MTP (Medical termination of pregnancy).

11) Anatomical examination of uterus, cervix, fallopian tubes and ovaries.

Apart from Obstetric ultrasound in the first 12 weeks, a special scan called Ultrasound NT NB is performed to screen for fetal abnormalities in the 1st trimester. It is an optional ultrasound and is usually done in high-risk cases or if any suspicion aroused during the 1st pregnancy ultrasound.

Ganesh diagnostic and imaging center is offering 50% discount on NTNB scan.

2) Second trimester- It includes week 13th to week 27th of pregnancy. During this period your obstetrician will order an anomaly scan or level 2 ultrasound scan for you. Level 2 scan can identify congenital malformations and fetal growth abnormalities. It also detects placental pathologies, helps in planning the mode and time of delivery and evaluates if there is any need to terminate pregnancy.

Anomaly scan, Level 2 ultrasound is done to evaluate or rule out the following conditions:

A) Fetus findings

1) Aneuploidies such as Down syndrome (Trisomy 21)

2) Anencephaly

3) Congenital heart defect

4) Omphalocele

5) Spina Bifida

6) Cleft lip

7) Renal agenesis

8) IUGR (intrauterine growth restriction).

9) Different Fetal parameters can also be evaluated such Fetal cardiac activity, gestational age of fetus, fetal weight, Fetal position etc.

B) Placental conditions

1) Placenta previa 

2) Bilobed placenta

3) Placenta accreta

4) Placenta succenturiata

5) Battledore placenta

6) Vasa previa

7) Velamentous cord insertion

8) Two-vessel cord/Single umbilical artery etc.

C) Maternal conditions

1) Cervical insufficiency

2) Amniotic fluid volume

3) Multiple pregnancy

4) Uterine fibroids

5) Assessment of uterus, cervix, fallopian tubes and ovaries.

3) Third trimester- It includes week 28th to week 40 of pregnancy. Swellings in your feet, pelvic discomfort or Braxton-Hicks’s contractions are more pronounced during this trimester. If you feel less fetal movements or no movement at all then your obstetrician may order a special scan for foetal monitoring.

How can I check if I am pregnant or not?

Pregnancy can be detected by Urine pregnancy test (UPT) which checks for the level of HCG (Human chorionic gonadotropin) in urine. HCG is a hormone produced by the placenta. HCG level can be evaluated in urine as well as blood. However, due to convenience in checking urine HCG through UPT kits even at home, it is more commonly used.

Once you tested positive for UPT, you should fix an appointment with your obstetrician. Your obstetrician will order an obstetric ultrasound scan to confirm pregnancy and evaluate your EDD (expected delivery date).

How many ultrasound scans are required during pregnancy?

Most heathy women with normal foetal parameters, usually undergo at least two ultrasound scans during pregnancy. First ultrasound scan is performed as early as possible during pregnancy to accurately estimate the various fetal parameters such as:

1) Gestational age

2) Site of implantation

3) Fetal cardiac activity

4) EDD (Expected date of delivery).

The second ultrasound or Level 2 ultrasound is usually done in later trimesters of pregnancy to:

  • Monitor Fetal growth and development
  • Check the position of placenta
  • Check amniotic fluid volume
  • Check the position of umbilical cord
  • Screen for foetal, umbilical cord or placental anomalies etc.

However, multiple ultrasound scans may be required during pregnancy depending upon various factors such as

1) Abnormal growth and development of foetus

2) H/o complications in previous pregnancy

3) Maternal diseases such as Diabetes mellitus, chronic kidney diseases, seizure disorder.

4) Gestational diseases such as-

5) Any specific condition identified during current pregnancy

6) History of recurrent abortions etc.

a) Pre-Eclampsia

b) Eclampsia

c) HELLP syndrome

d) Acute fatty liver of pregnancy etc.

How early can ectopic pregnancy be detected by ultrasound?

Ectopic pregnancy is defined as implantation of fertilised egg/zygote at an abnormal site such as fallopian tube, cervix, c-section scar or ovaries instead of the uterus.

Risk factors/causes of ectopic pregnancy includes:

1) Pelvic inflammatory diseases

2) H/O previous ectopic pregnancy

3) If Pregnancy occurs in presence of Intrauterine devices (IUD)

4) Tubal sterilization/ligation

5) Infertility

6) Genital tract infections

7) Smoking 

8) Salpingitis isthmica nodosa

9) Prior h/o intrauterine procedures such as Dilatation and curettage  (D & C ).

10) Multiple sex partners

11) Poor genital hygiene

12) Maternal age <18 years or more than >35 years

13) Assisted reproductive technology(ART)etc.

Symptoms and signs of ectopic pregnancy

1) Vaginal bleeding

2) Dull or sharp abdominal cramps

3) Nausea and vomiting

4) Tenderness in Adnexa

5) Adnexal mass

6) Cervical tenderness

7) Backache etc.

Complications of ectopic pregnancy

1) Rupture at ectopic site

2) Shock

3) Heavy bleeding

4) Recurrent ectopic pregnancy

5) Miscarriage etc.

Differential diagnosis of ectopic pregnancy

1) Acute appendicitis

2) torsion of ovaries

3) Miscarriage

4) Cysts in ovaries etc.

Diagnosis of ectopic pregnancy

Ectopic pregnancy can be diagnosed by

1) Beta hCG (human chorionic gonadotropin) levels in blood

2) Pelvic ultrasound

3) Transvaginal ultrasound- can detect early ectopic pregnancy as compared to pelvic ultrasound.
