I had unprotected sex three days ago (twice) and I let him ejaculate inside of me. I got my period today (like normal) but I am still worried that I might be pregnant.

Break down:

Fri Nov 23- had sex
Sun Nov 25- got period like normal

I would say no. You probably weren't fertile.
Why in the world would you want to put yourself in this position? Protect yourself!

I think this time you can count yourself lucky,

You sound young - just make sure your careful next time!

Good Luck

Well at least not pregnant, of course that does not mean there can not be some STD since there was no protection.

It is like playing with a loaded gun, you may not be gotten this time, but if you keep doing this, it will happen.

You had unprotected sex; you could be pregnant. Don't want to be pregnant? Don't have unprotected sex. REALLY don't want to be pregnant? Don't have sex at all.

Just to clear it up for you guys who have answered me, he is my fiancé I've been with him for 6 years and I'm 21... so I'm not crazy for the unprotected sex part.

Okay, so you have been together and all that - Do you want to be pregnant? Are you ready for a baby in your life?
You play with fire - you get burned.
