dear Dr,I am a lady longing to have a child.i had 4 d&c's.
First time i conceived naturally but i had partial molar pregnancy,i cleaned by using tablets.Secondly(natural conception) i had blighten ovum,my OB did D&C.We did karyotyping,TORCH,Screening tests,diabetes,thyroid,std tests everything everything normal.As i had Artificial insemination my Dr was watching the Progesterone,LH,FSH frequently on all 2nd day of menses cycle and was giviing medications accordingly.
Afterwards as there is no result i changed my Dr after 2 years.
My new gyn Dr did Hysteroscopy both tubes are normal.i had ecospirin,m2tone,progynova,clomid etc.,i conceived by Artificial Insemination but now it came as ectopic pregnancy and i take methotroxin injection(no surgery was needed).
Later she did analytical Laproscopy She told there was a block and the tube where i got ectopic.So we concentrated on right side ovulation time.We gave a gap for 2 months and i pregnant naturally but this time my hcg was not increasing as much he expected. She gave progesterone 100mg ,i was taking bed rest on 42nd i got ultrasound scanninig it was normal gestational sac is normal.but on 45th day i got spottings.On 49th on u/s there was no fetal pole and yolksac began to shrink So i undergo D&C again.
I now want to know whether i can give birth to a child?some of the drs suggesting heparin after getting pregnant and other telling iam not under that category my APS is normal so no use in taking heparin.plz tell me if i have to perform any tests i am ready to undergo it.Please give me a solution for this.i'll be very thankful to you if you could answer me.

Repeat pregnancy loss is emotionally draining, and when no specific cause or treatment is identified, it is very frustrating as well. I am sorry to hear that you are having to cope with this issue.

The good news is that many people with your history go on to have normal, healthy pregnancies resulting in healthy babies. Unfortunately I can’t give you the answers you seek in this forum. None of the issues you describe points specifically to an easily identifiable problem. The most common genetic tests and considerations for repeat pregnancy loss as described by several genetic and obstetric professional organizations are below. You may want to discuss this with your healthcare provider to verify that the following list was considered for your circumstances, and discuss if there are any other non-genetic tests that make sense for your specific situation.

• Parental chromosome analysis
• Analysis of family history and ethnic background for clues related to repeat pregnancy loss
• Testing for inherited thrombophilia (blood clotting disorders) such as Factor V Leiden, Factor II prothrombin, and others.
