SO LOST!!!

Okay so I just recently lost my child in July and I've been having normal periods. When I had my cycle last month I had it for 7 days and I was in a lot of pain. After a few days I spotted and as of this month I'm late and I've been feeling like crap.

I was spotting for a couple of days last week plus my pain feel like labor pains. I've also noticed I have pain only on the left side of my body. The left side of my stomach,pelvic,back and leg hurts really bad.

Yesterday my shoulder started hurting and my head hurts as well. Today when I used the bathroom i noticed light bleeding and I felt like I was having a baby(that urge to push). Please help I don't know what to do I'm worried.
