I am 37 year old and my husband 38 years. I am trying to conceive since last 4 years. My TSH report normal. Hsg of tubes showed normal tubes but there wad some infection. Although tb pcr report normal the doctor put me on ATT for six months. I completed course inSep 2011 and tried IUI in Oct but did not conceive. I conceived naturally in feb 2012 but blighted ovum and miscarried naturally. Then again conceived in sep 2012 naturally but the foetus did not grow beyond six weeks. No cardiac activity. Miscarried naturally on30 Nov 2012. The karyotyping of foetus showed tetraploidy. Then tried IUI in june 2013 but did not succeed. Had hysteroscopy in july 2013 and report was normal. Had again IUI in sep 2013 and failed. Again conceived naturally in dec 2013. But the scan showed twin gestational sac and monoamniotic and monochorionic pregnancy. Only one foetal node with cardiac activity seen at 7 weeks. During scan at 9 weeks the foetal node had no cardiac activity and growth stopped at 6 weeks gestational age. Had d&c on 1st feb. I was takin susten 200mg and aspirin 75 mg daily and folic acid during pregnancy. The foetus tissues have been sent for karyotyping and report awaited. Please advise me further course of treatment.

### output:

Hi there, I have gone through your question, and I think I have understood your concern. . I will suggest you the best possible treatment options. Please do not worry. It is sad to hear about your previous pregnancy losses. Please note that you are able to conceive , only problem seems to be that with continuation of pregnancy due to various reasons. I will suggest getting genetic testing with karyotype of both of you. As before, please keep B 12 and Folic acid supplements as before.  As hysteroscopy findings are normal, structural causes related to uterus are ruled out. I hope this answer helps you. Thanks Chat Doctor.
