Kinda scared

I had sex today. 3 rounds of it. Its been 5 hours since last round and my stomach has been in pain and when i went to pee blood is coming out. Its not my period bc i just got off it. Back in may i was diagnosed with chlamydia and ive had it treated the day after i found out. I read online that bleeding could happen after sex with chlamydia but also with pid. Should i get checked out for pid?
