Help please! Important


So Im on the birth control implant thing and I have recently gotten a UTI and I had a little bit of blood in my urine. I’m also 2 months late on my period and today I started bleeding A LOT I don’t know weather I started my period or it’s the UTI? When I’m on my period I usually get bad cramps and throw up and stuff but none of that happened so I don’t know weather it’s my period or not? Can someone please help cuz idk if I should go to the doctors or not if it’s just my period but I positive I have a UTI but the other stuff idk?
