Period or miscarriage or pregnant?


So my period was 5 days late. I had noticed that I had some pregnancy symptoms. Cravings,stomach cramps, fatigue, head ache, sore breast. I was going to take a test on Tuesday but yesterday I started bleeding. The cramps have gotten worse it feels like someone is stabbing at my uterus. I don’t get cramps with my period and the bleeding now is light with some clots. Just confused because the only time I’ve ever felt this bad was when I found out I was pregnant with my kids.
