Isabelle • Majoring in dog grooming and dog training

Okay so I got my IUD 10 days ago and have been having my period since, that’s fine not the issue. Anyways I have sex with my partner tonight, first time since getting IUD. It was great it was raw but he pulled out and it was doggy style. Now to the issue. I go to pee and I’m wiping and I notice blood on my jeans (wasn’t wearing underwear cause I was going straight home) and my thighs and when I’m wiping I’m wiping blood. And it’s red blood not the brown blood I’ve been experiencing since receiving IUD. Did I mess up my IUD or anything? Why am I suddenly getting red blood?
