I had sex almost every day of the week I was ovulating (July 1-10). I used condoms in each session.

I took two pregnancy test on Monday, four days before my period was due just to be sure and they came out negative.

My period is usually spot on every month, on the 19th. Today is the 21st, so I am technically three days late.

I have not been feeling nauseous, but I do get random hot flashes, back aches, and random cramps.

What do you think? A possibility I might be pregnant?
