How to ask someone if they stimulate themselves?

So today I masterbate and after I orgasm I went down to whip myself I seen a spot a light red blood I thought I started my period but usually I would start cramping first, my period doesn't start after 20 days in a new month But ! A couple days before Valentine's day I did have sex , once ! no condom. Since then I've been on a craving food , been very tired ..could I be pregnant ?

How long after your last period was the sexual intercourse? (if was between 8 and 14 days after, than there is a good chance you may be pregnant depending on the length of your cycle) Wait until your period is due and if it doesn't start take a HPT.
