Weird period?

Megan
So I started my period Sunday, and it was really light barely anything but still red blood, Monday was a bit heavier, more like my usual flow, and now today it's A LOT of mucus mixed with the blood and it's still light and not really a flow.
I'm really really worried that I'm pregnant or something, but I know I probably can't be.
My boyfriend and I had sex a week and a half before my period but it was for five minutes and with a condom and we checked for holes afterward.
I'm also scared maybe I had given him a handjob during my fertile days and then went to the bathroom and touched myself and that caused me to get pregnant.
Am I worrying too much?
I'm nauseous and crampy and just all around feeling bad. I lost my appetite and I'm worried sick.
Someone please help😭 I'm googling things and it's telling me stuff about pregnancy and miscarriages and implantation and I'm still freaking out. I don't really know what to do.
