Period

Hi everyone. I asked a while ago but I didn’t get any reply’s. Thank you if you do!

Me and my partner have been having sex like three times a week without protection. He has been finishing in me. The thing is in the month of February a week or so in i got my period and we did it then too. (Sorry tmi) well I’m going about my life normally. And the 25 of February I feel a blood clot just slightly slide out. So I get up and I have this bright red blood coming out too. And I’m sitting there confused because I already had my period. I took two pregnancy tests but regardless it would be too soon to know. At this point it’s nothing like my regular period. It’s not heavy much of it is just spotting unless I have sex then it will come out heavy for a good minute. And stops. My regular periods are always heavy flow. I’m just concerned at this point. So for making this so long.
