Idk anymore

I thought I was pregnant not far long. A lot happened between my boyfriend and I and it wasn't good. I've been cramping here and there and it feels like growing pains in my legs and I just don't feel pregnant anymore. I've had 3 miscarries already and now I think it's happening again. I'm over this I'm over him pushing me to stress like I do so I'll end up losing the baby. He doesn't care, also we never have done anything to prevent it from me get pregnant and now that I am or was he doesn't want it.
