• Implantation at time menses
• Cervical trauma during intercourse
• Subchorionic hemorrhage
Can trans Abdominal U/S detect ectopic pregnancy?
No, only trans vaginal
How you manage Ectopic Pregnancy?
If the patient is stable ~> MTX (HCG < 5000)
If not (ruptured tube) ~> Surgery (Salpingectomy & Salpingotomy)
What associated with Duodenal atresia?

Bulk symptoms (rectal pain or pressure) + cervical protruding mass + heavy vaginal bleeding =
Cervical leiomyoma
Vaginal bleeding + High HCG + Enlarged uterus =
Choriocarcinoma
Amenorrhea + Blind vaginal pouch =
Complete mullerian agenesis
Abdominal pain + Foul smelling vaginal discharge + Vaginal bleeding + something seen in vagina on exam =
Foreign body
Postmenopausal woman + Pelvic pressure + Vaginal bulge increased with valsava =
Pelvic organ prolapse
Infancy + Polypoid or grapelike mass protruding through vagina + Vaginal bleeding + Vaginal discharge =
Sarcoma botryoides
How B-HCG change during pregnancy
Double every 48 hours
Peak (100k) at 8-10 weeks
Decline until 12k in 20 weeks
How you determine fetal age by U/S

- BPD
- FL
- HC
- Abdominal circumference
How you determine fetal age
- LMP
- 1st U/S
- URINE OR BLOOD TEST
- FETAL MOVEMENT
- SFH
- LAST U/S
- PATIENT OPINION
When SFH mismatches with fetal age

What are 1st trimester screenings
- BMI
- Blood Pressure & Serum glucose level
- CBC (exclude anaemia + establish baseline)
- Blood group & RH
- GUE & Culture
- Infections
1- How you detect allo-antibodies between mother and fetus
2- why you wanna know blood group of pregnant woman
3- when we give anti-D rather than RH incompatibility
1- Indirect coomps test
2- Blood transfusion
3- SAB & Amniocentesis & Trauma
How you determine RH group of the fetus
- Cell free DNA testing (in mother’s blood)
- Amniocentesis
If MCA doppler of baby reveals High flow, it means:
Fetal Anaemia
