Chances of me being pregnant? Sex on 12/15, ovary pains 12/

I had sex on 12/15 with protection. I started to get pains in my ovaries on 12/16. If the condom broke (which I don't believe did, but Im thinking worst possible situation), what are the chances im pregnant? When should I start to worry about being pregnant? I'm very uneducated on pregnancy, so any help is appreciated.

Okay, let me eduacte you on pregnancy..

Pregnancy is not INSTANT, it takes at least 6-8 days for pregnancy to full occur, up to 2 weeks in total.

This is why you are told that you can start taking a pregnancy test about 2 weeks after sex.

FIRST the egg has to be fertilized, which takes 2-3 days, again, NOT instant. Then it has to go to the uterus and implant, which takes up to 10 days...

IF you are worried about pregnancy, you cans till get the morning after pill, which can be taken up to 5 days after sex. Planne dParenthood sells these inexpensively.

Regular birth control is also important.
