OK can someone help me please? My period is always on time which is the 1st, I had sex on the 12th of January 2014 and this month which is February Of 2014 I was 1 day late. My cycle is usually heavy when I awake in the morning but this morning it was a pinkish brown spot on the tissue when I wiped. Now the blood is turning fully red. Should I be worried or is this my period?
