Provera/Progesterone

CC

So long story short I was prescribed provera/progesterone to induce a period since I have irregular cycles. I’m on my 6th day of 10 days of taking it and today and yesterday I was having mild cramping in my pelvic area. Has anyone experienced this? Could this be related to the provera? I also haven’t had any of the side effects from it and I’m not sure if that’s good or not. In the back of my head I’m wondering if I’m pregnant but I know that’s a very slim chance
