PERIOD HELPP PLEASE REPOND

ok sorry for the title lol

no one EVER replies back so i need someone to pleaseeee!!!!! so basically my periods are usually pretty heavy and last about 6-7 ish days... and i was in sports and worked out for a while before all of this corona and so now i haven’t been very active. my last period was AWFUL it was sooo much blood and sooo many clots and it was terrible. my periods are heavy but thag was like a murder scene in my coochie!!! so fast forward to this period.. about like four days before my period was abt to start i just started to get back to working out n stuff and i heard that can effect ur period with flow n cramps. so now my period was two days late and i’ve been on it since this past wednesday and it’s never been this light. yeah it’s filled tampons and pads but it’s sooo much lighter and it seems to almost be done because it’s soo light. it’s still a little clotting here and there but nothing like before or after. it started out brown and got to red. i also had sex this cycle unprotected and protected but he always pulled out... so i’m wondering if i could be pregnant or if it’s the exercise ???
