Wtf is going on? Could i be pregnant still ?😩

So a history of my periods. Ive had the SAME cycle since i was 14. Im now 20. Theyre 4 days long and super heavy looks like a crime scene type shit. Well my last one was march and it was a terrible one i had to go to the er for cramps and thats how it is every cycle for me. Well april comes around and i completely miss a period that month and my SO finished in me on the 6th, 8th and again on the 22nd. I guess i ovulated later than i thought. May 4th (almost 2 weeks late) i started bleeding again but this time i realized around day 3 that it was pretty light and pink the entire time! I was using 1-2 tampons a day instead of bleeding thru 3-4+ a day!! Could i still be pregnant? From the days we DTD and the time i ovulated? I know i forsure ovulated that week because i was having little ovary cramps and CM.

P.s i took a pregnancy test at 3 days late (at the time i thought i ovulated earlier than i actually did) and that would’ve been too early to test obviously)
