BFP after recent ectopic!??

Kristen
My husband and I TTC for 20 months until we found out we were pregnant this passed Jan. However, everything spiraled out of control when we found out that pregnancy was ectopic. I was run in circles with no answers for a month, until my tube ruptured and I was bleeding out! The doctors recommended that we do not TTC for 3 months because of the ectopic. I had my surgery (in which they were able to save my tube) on Feb 19th.... We decided this last month to not use protection, since it has been 3 months. My thought was "there is no way I'd get pregnant again that quick anyways." We have never had an easy time getting pregnant.... But I took this, this morning!! I am 10 DPO, for sure, because I had a confirmed Ovulation from our OB who was following me since the surgery. Is there ANYTHING that can cause a false positive?? I am so scared that I am in denial! And I am 90% sure I ovulated from the side in which my recent ectopic was! Did any of you mommies have a successful pregnancy and rainbow baby shortly after tubal surgery?? I can't believe it! Doctor's appt is scheduled for Thursday, if all goes well, surprising my husband for our father's day celebration this weekend! TIA!
