Am I Pregnant?

Hey guys, so on March 24th my boyfriend and I were messing around. He didn't insert his penis into me, but he kinda rubbed it on my vagina. He was also fingering me very hard.  He didn't even ejaculate.  Since then I've been really paranoid. My period came on as usual (comes on like clockwork) but it wasn't as heavy as usual. It lasted the whole six days, and I experienced period symptoms. It always comes on during the first week of the month. Although my period did come, I'm still concerned. I have no symptoms,  and tomorrow I'm taking a pregnancy test. Is there a possibility I could be? Or nah? Am I'm overeacting?
