URGENT PLEASE REPLY

I got my period this month, four days ago but it's been really light, barely anything and mixed with mucus there have been a few clots.
It's ending now I think and I feel really sick and hot and my boobs are still kind of swollen.😔
I keep googling things about how a light period means you're pregnant. My aeriolas seem darker than usual. 
I did have sex a week and a half before my period but it was protected with a condom and he didn't ejaculate and we checked it for holes after 😭
My boyfriend is worried about me.
The only other thing we had done this month is I gave him a bj during my fertile time and now I'm scared I touched myself in the bathroom after I did that and may have gotten sperm on my hands 😔
I'm literally terrified and don't know what to do
