Could I still be pregnant?

Okay so I had unprotected sex (stupid yes I know) and my period was late by like a week or two but I just got it two days ago. The first day I randomly started bleeding halfway through the day after I peed and I was like okay I got my period. It wasn't spotting. It's actual blood. Not dark red or pink, it was regular. The next day I bled all day. Today I bled until around dinner time. Now I wipe and its only pink like I'm getting off. Normally my period lasts four days and it's heavy. My last cycle was the same way. I had sex w a condom though and he even pulled out w the condom on so it's very hard for him to have gotten me pregnant. The last cycle was two days of bleeding as well. Ive only recently become sexually active recently (before last cycle and this one.) I've been very very stressed that I might be pregnant so maybe that's why I had weird periods these last two cycles. I took a pregnancy test over two weeks after I had sex last and it was negative. Maybe I should have a blood test? I looked up how much they are and planned parenthood had them free I think?
