My man and I did the deed yesterday morning and had a pretty good session. I say "pretty good" because I haven't been this into it in so long. While he was at work, when I'd use the restroom, I had brownish discharge (nothing new) and assumed that was from how into it we were. This morning, I used the restroom and saw that I'd started my period about 2 weeks early. I've been regular for a few months now with 35 day cycles, so it was shocking to see how early I was. Is it possible that sex made my period arrive so soon? Is this a thing?
