I think i may have an STD but im not sure...Read my body and tell me wat you think?

Ive had with 5 ppl.One i did not use a condom but i told him not to go for that long.I am on birthcontrol so thats not wat im worried about. I had 3 days in a row. and my bodys not used to that.I usually wait a week or two. And tha person b4 my last, wantd to try . And ive never had that b4 so i feel like irritated..kinda feels like i gota hymroid.And sometimes i hav a VERY small amount of discharge,sometimes it contains a small amount of blood but its more on tha pink side.I dont know if he jes went so hard and fast that he like ruptured somethin or wat.And tha day after, i had again wit someone else and he was pretty rough wit me thn too and tha day after that. And sometimes it burns whn i urinate.But i think im jes irritated cuz im not used to it. But idk..... wat u think???
