Morning after pill experience?!

May

Okay so 6 weeks ago i had unprotected sex (by accident) the day after i took the MAP. Four days after that (i think) i had my period. My period is very irregular and the flow can be mild or just like spotting for a couple of days so i could really know if it was something else like implantation bleeding.. Now it has been about 37 days since my last 'period'. This isn't necessarily late because of the irragularity. I have to pee ALL the time and i got really weird cramps yesterday, it could have been anything but the symptoms were very very similar to a ectopic pregnancy.

I am almost certain i'm going to buy a test, no one else is able to do it since i can't tell anyone about this guy (i made some very very stupid decisions). I have very bad anxiety and even when i go out to get shampoo i'm really paranoid. But well yeah i will still have to get it i guess

Does anyone here have had a similar experience with the MAP? Did you get pregnant? Or am i overreacting?

I would really appreciate any response!
