TMI sex/masturbation bleeding

Victoria

So I got a mirena iud at my pp appointment and my husband and I had sex 4 days later (with a condom). I didn’t get off and I’ve become physically uncomfortable from the build up of not having sex for 7 weeks. So I tried to masturbate the next day (no penetration), and still couldn’t get off, but now I’m spotting. And when I wipe the toilet paper is covered in blood. I’m just a little crampy no actual pain. Has anyone else experienced this?
