10dpo and BFP!!!

well, today is the first time in my life that I ever took a pregnancy test and it said Pregnant!! I just have been feeling weird, breast tenderness, frequent peeing, cramping, etc., and so I decided to take a test this morning just for the heck of it and it was a BFP!!! I am cautiously excited because I called the RE and they said that they can't rule out the "trigger" giving me the positive, even though I have previously tested on 10dpo and got BFN, so I'm very optimistic. All of the boards on the nest...TTC, success after IF tell me they have see this before and the drugs should be out of my system. I sure hope so!! I'm going for bloodwork on Thursday morning, I hope it says the same thing!
