Hello Doctor I have been trying to conceive for 2.5 years now. Have got all tests recommended by the doctor done such as hormone test, thryoid, lipid, iron profile, ovulation test, test to check blockages in fallopian tubes and husband's sperm analysis. Everything has come out normal. What can be possible reason for my repeated failure to conceive? I do not have a regular cycle, 30-50 days. This cycle, however is currently on day 89. I have a few out of the ordinary symptoms, backache since the last 3 weeks, gas and occassionally frequent urination. I had a lab urine test done on day 85 and it came out negative. Will appreciate your advice. Thanks.
