Pregnant? Please read and comment!!

I had about 5 days ago. I gave him a blow job beforehand and he came. We had sex after that and he didn’t cum in me (but came a second time on the sheets). I’m thinking he “pre-came” inside me.

We didn’t have a condom and I’m not on any birth control, it wasn’t really planned at all.

The next morning I took a plan b just Incase but barely had any symptoms. Is that a good sign or bad?

My fiancé left a few days later for a 2 year long trip in a foreign country (probably why we impulsively had sex, knowing we couldn’t for a long time). I couldn’t go with him as I just started college. We’re young to be engaged let alone pregnant... and I’m afraid that if I am pregnant I will have to raise the baby alone since he is out of the country for a while.

I guess I wanted to tell someone as NO one knows that we had sex. It was a bad idea considering that we had no birth control at all. ALSO wondering my chances of pregnancy, I know they are low but I’m still nervous.
