Ok me and my bf had sex two weeks ago around that time I just finished having my period, the condom broke and I was like ok crap started to get paranoid and to be on the safe side he bought me the plan b pill just in case the iud stuff didn't work and I took the pill the same day we had sex . So on Monday morning I woke up  sweating feeling like shit then I had to pee after than I got dizzy and started to puke, and yesterday  I was spotting.Idk if I am pregnant or if it was the food I ate at  the restaurant where I went with him on Sunday I'm just freaking paranoid about getting pregnant I'm not ready to be a mom yet . I just need some answers or advice
