So, I took a plan b pill last two months ago on Feb 15th. And gotten my period for on Feb 18th for 8 days. Then in March my fiancé and I had unprotected sex every other day because we decided to have a baby. Then when I'm supposed to start my period but I was only spotting for three days then it stopped. And took pregnancy test when I stopped spotting and it came out negative.. And now I'm in April and still hasn't gotten my normal period yet. I didn't want to take pregnancy test because I was assumed that maybe plan b mess up my period cycle.. What should I do?
