Hi there, I'm turning 23 this month and already have one child. I had my first and only depo shot June 19th, I was due for my second shot September 18th but didn't get it, and have been without birth control since. I got what I think might have been my period October 23rd, but it was pinkish and very light, lasted 7 days though. I have always been told ovulation is 11-14 days after the first day of your last period, and I had unprotected sex with my bf I think on the 11th day. On November 5th I started real lightly spotting, so my question is even if I had unprotected sex while ovulating and spotting lightly now, is there any chance conception could have happened?
