so about five weeks ago I had unprotected sex no for very long and he didn't cum in me but I'm worried about pre cum. Also I ended my period the day before August first and on August first is when I had sex I took plan b that same day about 4 hours later and another pill on August third. 10 days later from the first day and 8 from the third day about a week I guess I bled for 4 days which as long as my regular period. But I found out it wasn't my period ? And now I'm worried because I should get my period at least by the end of this week which is Sunday but I don't know what to do and I'm scared
