After having sex I was spotting and that was about it for the rest of the night. The next day I had light bleeding & then it got heavier as the days went on. My periods aren't usually too heavy.

Would u consider the day I had spotting from sex my first day or the next day where I actually had heavier bleeding?

I'm trying to conceive and don't know if I'm late for my period or not.

The 12/31 is when I spotted after sex and 01/01 is when I felt like I had my period.
