Hi. I had my period in october. I have a regular cycle. According to my calendar I keep track of my fertile days were from the 1st-6th of November. Ovulation was supposed to be on the 6th. I had unprotected sex on the 3rd. My period isn't due until the 20th. I went to the bathroom yesterday and when I wiped there was light blood. Today there was a litfle but barely any at all. Could I be pregnant?! I am worrying myself to death it seems like!
