I had unprotected sex with my partner a little less than a month ago. We had unprotected sex a bit after my period ended. hours later I took plan B, and took both pills at the same time. My period was due on October 19 and it is now Nov. 1 and no period. I have had cramps and feel has if I had my period but no blood comes out. I was stressed out all last month, I cried alot and stressed over many things. Is that affecting my period now?
