I have a question about fallopian tube blockages. I was able to get pregnant very quickly about 6 months ago but then miscarred at 10.5 weeks. My partner and I decided due to our ages that we would be proactive about determining if there was an underlying cause rather than waiting to see if the next one "took". All tests were good, FSH 5.8, lots of nice little follicles developing eggs, good semen, EXCEPT for the one I was least worried about-- the HSG. It showed that my tubes were block. The doctor said not to worry since I'd gotten pregnant so fast, that maybe one or both were not as blocked as the HSG showed. But I'm confused, how is it possible that I got pregnant (non-ectopically) if the HSG showed that my tubes would not even let the dye keep going ??
