I had unprotected sex the 31st of July, he pulled out. It was my first time so I felt alittle strange after on the 3rd of this month I took plan b just to be safe, about a week and a half later Istarted what I thought was my period it it was super light almost no blood so I am guessing it was spotting ? Anyways now I am waiting for my period and I have been gettin little cramps in my lower belly and my stomache in the same spot is kinda proofed out I get nauseous sometimes and headaches and I had a yellow discharge not a lot am I just over thinking ? I am so scared
