Hi I m 32 yrs-female,wt-60kgs,ht-5.2.I had no infertility problem. I conceived in the first chance thru IUI in may 2010 and after 2 mnths of pregnancy i had a missed abortion which showed trisomy by the FISH test.since jan 2011 i have been trying to conceive naturally-3 mnths and thru IUIs-2 mnths,with full medical intervention,but unfortunately i hav not conceived yet.All these 5 months follicle monitoring was done which showed good ovulation and endometrium .my husbands sperm count and motility is also good as per the doc.For the last 5 mnths due to stress i have become prediabetic with slightly raised fasting sugars which were taken care of with medicines.as per the doc now since every thing is in good shape and inspite of two IUIs i have not conceived, she is of the opinion to get my tubal patency tests done. i need to know whether this is the right decision to get the tubal tests done. since I have already conceived once,are there chances of tubal blockages now.what is the best procedure for these tests without any effect on the uterus and ovary .I am planning to have the tests done this mnth after my periods by 18-19th may 2011.pl advise. im toooo confused.I m a science postgraduate. I am fully aware of the human body.i need the answer on priority basis to to be able to take a decision.thanx
