Well,
sorry if this seems naive, but yesterday I had sex with my boyfriend.
and My period is usually supposed to come around the 20th or 23rd of a month. We had sex on the 2nd.

now, is this a fertile time?
I dont think so, but im worried because
the day before I started to get pretty turned on, and i dont usually... only when im fertile, right?
and today im getting light cramps.

What are my chances of being pregnant?
