help

can someone help me out lol so basically I had s3x on january 22nd and my period was already late by then because my periods are irregular so I never really know when ima get them but basically we had unprotected s3x and we lasted about less than 20 seconds but im scared he could've pre ejaculated in me he said he didn't but idk. I ended up getting my period on january 31st and my period was heavy with clots and that lasted about 2 days till it got lighter all of a sudden even though it never does that but small clots still came out and it lasted 7 days like usual. But now i started feeling lower abdominal pain but it feels mild and pelvic pain and my pee is clear even though I hardly drink water and ive been feeling way more bloated than usual or maybe cuz I hold in my pee for too long idk someone help pls
