Lets see...I had unprotected sex may 5th and I took plan b that Monday afternoon, I'm new to all this ECP deal & don't know much about it. I usually get my menstral cycle the 14-15 and I haven't got it yet. I have been experiencing some breast soreness, more so in one side than the other, I havens cramping and sometimes I think I'm getting my period and I don't, & sometimes gassy. I'm anxious and scared, I have a two year old daughter, I'm not ready for more kids...please someone help answer this question for me. Thank you in advance
