Early testing 🤔

My period is so out of whack from having pcos , but I've been on the pill which makes it regular. It's been 11 , 22 , and 24 days between periods That's that last 3 months . According to my tracker I'll get my period this Friday. My last period started June 24 an was 8 days long. I messed up with my pill the week I started my last period an just all around stopped Around July 4th . Fiancé an I are very sexual active as in usually once a day. I feel I'm having pregnancy symptoms from cravings , smells , a little bit of shortness of breath n tender boobs . July 10th we where having sex an there was blood but it was only that day an I never started my period ,  it wasn't even period blood it wasn't the same. I googled it and all signs pointed towards implantation . Help ! I wanna know if it's to early to test an if any one has tested before there period an how were the resulted ?!Â
