Needing some advice

Had a miscarriage at 7 weeks in May. I was so exited about having another baby since my son is Turing four in October thought it would be perfect. No the pregnancy was not planned at all but was very excited when I got that positive pregnancy test in April. It's been since May 16 that I've lost my baby. And I'm still having a hard time to the point I know how far long id be if I was still pregnant and how I hate being around pregnant women. My bed and who was the father of the baby I lost has acted like it was nothing and no big deal. I've been trying to act like it doesn't bother me anymore but doesn't seem to be working out for me. And on top of that I just feel like I have no control over my body. Had two normal cycles in June and July and now I'm spotting where I stop then I spot again been like this for three days now and my suppose to have my period till August 12. I just hate that I'm no longer pregnant and that my body is just completely out of whack. Is this normal I've never had a miscarriage before so this is my first and it hurts a lot
