period?? help please!!!!!

so I had my normal period February 25th until the 2nd which is my normal period (light to medium like always) . so then I had sex on Friday the 6th issuing protection. I started ovulation the 7th and I kept track of it on my glo app. so then on the 8th i began bleeding. I thought it was spotting, but I never really spotted before during ovulation. well now it is really really heavy. I am bleeding through super plus in 3 hours. is it my period? what is wrong? please help!!!
