Hi,
21 years old. I was 10 days late on my period. I am usually 2-3 days late but this time I was scared. I had unprotected sex last month. (I know, I was silly) ( he pulled out before finishing). I took a test 2 days before my original expected date for period and it was negative. I then took one 4 days after my expected period start date and it was negative. I had no symptoms other than my usual period which are headaches and sore breasts. My period however was heavy on the second day (yesterday 18/10/2016) and now seem to be going. I was wondering if i should be worried about anything?
