You certainly could be pregnant, but like you know, it's rare. It's more likely caused by the TL. I've never known anyone who has become pregnant following a TL, though it does happen-generally with more than 50% being ectopic, from what I've read. What I've found more, is countless women saying "wow, I had all those problems after my TL, too..I never knew it was related!" Some older than 50 who dealt with it for years.
I was always an extremely regular, no problems in the "female dept" kinda gal. Well, I had my tubes tied via filshie clips at the birth of our 4th child. Long story short, but I was scared into the "too many c-sections" deal with her (she was my 2nd section and forced for a VBAC ban) and rude comments about our family size/spacing.
Immediately..I mean, immediately, I began having problems. My milk supply had issues, then the migraines began. Then, each month I felt very pregnant for 1-2 weeks before my period would arrive. My period would come every 21 days to every 35 days-odd for me. I would spot for 5 days before it arrived, and sometimes at ovulation. My labs were normal, yet I could tell I was experiencing major progesterone and hormonal imbalance. On top of that, I bled so heavily for AF I had to be on iron supplements when I normally have had NO issue with iron, even in pg and birth.
I didn't regret the TL yet at the time, as I still convinced myself it was "the best choice". So, I began seeing my OB and then my DO and then a naturopath. They all came to the conclusion I had PTLS, and suggested a reversal. The insurance company also agreed my heavy/flooding, painful periods and migraines were likely due to the TL. However, they wouldn't pay for a reversal, since it isn't covered in our policy, and suggested a hysterectomy. At that time I was 28. No way was I having that. About that time, I also started to regret closing off our fertility, and it really became difficult to bear pregnancy symptoms with no baby.
I sought out reversal, and we began saving. We went to the best possible place that specializes in ONLY TR. We went out to Chapel Hill Tubal Reversal Center in NC. Dr Berger and Monteith. I had my TR on 7/30/08-3.5 years of hell after TL. We waited a month to fully heal, and then I got pregnant in September. I had him in June of last year, and now I'm pregnant again.
I had only 1 period since TR, and it was fantastic, and I no longer suffer from totally debilitating migraines..
There are lots of ladies there who deal with PTLS on the message board. Maybe sign up for the board, and ask some questions and get some support. You are NOT alone in the area of problems following a TL!
Much Love and sympathy!
