Are these chemical pregnancies or hysterical pregnancies?

I've had several pregnancies this year but lost them all. I get sore boobs, moody, a bump and all the early pregnancy signs but no positive pregnancy test or blood test.

I keep calling them chemical pregnancies and miscarriages but my friend says it's just normal PMS and I'm just getting my period.

I want a baby so badly. Are these chemicals and miscarriages?
