Miscarriage

This is my second period after my miscarriage. And since then i just have funky cramps and my first period was super funky this one is a lot more normal and cramps are more normal. But is it normal to have a weird cramps and period for at least 1-2 cycles after a miscarriage. Because I’m fucking insane and I need to stay off the internet because I’m convinced I have PID. Someone please tell me I’m nuts. I have no symptoms of that other then I have cramps but I’m also on my period and I think my bodies still trying to regulate.
