I took the Plan B pill on the third day. I haven't had my period yet, but I'm noticing that my stomach is getting hard and a little bit bigger than usual. I'm not hungry, I don't have to go to the bathroom every second, my breast are not hurting or getting any larger, and I'm not experiencing any nausea of any sort. I'm not sure at this point what to do and I am stressing out badly. Can someone help me with this issue?
