I'm so sorry breakingdawn. It does suck. I wish it didn't. I get pains on my bad side all the time now. Sometimes excruciatingly and I've missed work several times for it. I'm assuming it's related to the scar tissue and ovulation, since that's when it happens. Though, there has been some question as to which side is actually my tube that was removed, because my doctor's reports are contradictory. I'm not sure if I can go back to the doctor that did the ectopic surgery and get a report now or not. That would help answer some questions.
Anyway, you don't switch back and forth each month, which can make it even more frustrating when planning. I think it's technically which side matures first. And it can be the left side two months, then the right once, etc. It's just anyone's guess and it sucks because you can't help in timing anything. It's good to hear that people had success with the other tube "picking up" the egg though. So that's a plus.
Get out your frustrations though. We are here and have to go through the same stuff.
I get so mad some months. Now I'm just happy to be moving onto IVF so I can by-pass the tubes all together, since they seem to be really non-functioning now in my case.
