Am I crazy!?

I had a miscarriage at 5w 3d on 11/19. AF is due to arrive on 12/21 (I know, still early). I started having all the same pregnancy symptoms I had last month when I tested positive... my boobs are swollen, cramping, heightened sense of smell, hungry all the time but not much of an appetite, crazy emotional, hot flashes, insomnia, bloated and increased urination. I tested positive 4 days before AF last month. I tested this morning (4 days before AF is due) and it was negative. I know it's still early to be testing but could these symptoms just be pms and left over hormones from last month? I have never been pregnant or had a miscarriage before and I feel like I'm just a crazy person this month. Please help a sister out, I'm so confused on what's going on with my body...
