Having a break down 😭😭

Jo`Alyn
Thinking I'm having a freaking miscarriage again. This last month I 100% felt like I was pregnant. Huge increase in appitite, literally ate everything in our whole house and I'm only 100lbs 😅 I had constipation that was soooo bad, boobs grew almost two cup sizes and were soooo sensitive. I was nauseous, some days I would throw up from coughing to hard, or a fishy smell would have me running to the bathroom, some days didn't feel too nauseous. Then I got my period. I was completely surprised cause I Forsure felt like I was pregnant. Had a normal period for 5 days. The whole time I still was constipated, still hungry, still nauseous and my boobs were still full. My period ended, and a week later when I'm supposed to start ovulation, I start spotting. It's my third day of this and I am now changing my tampon every hour on the hour and passing clots. Did I miscarry?... What would be another reason for this bleeding? Everything I looked up, is normal for spotting.. Not heavy period flow.. A week after I finished my period. Also I'm as regular as it gets for periods please help..
