..I m 23 years old, on the 11th I had unprotected sex a few times and 1 of the 3 he didn t pull out. Afterwards when I went to the bathroom, there was a very light reddish pinkish color when I wiped. I m on the pill but don t take them at the same exact time every day. On the 13th I had some cramping and bleeding, that had lasted now 10days. It was a reddish brownish color and if it was my period it was a week early. I was on my 3rd week of pills so I was confused as to why I d start that early, could I be pregnant?
