Ordinary

I’m 7 weeks & 3 days. I started spotting yesterday and I been at work for 24 hrs not doing too much but any who now I’m bleeding and it’s very dark. It’s mainly when I go use the bathroom. Urinating awfully a lot my stomach is hard like a ball and I’m still showing. I’m just worried because I do tend to stress here and there worrying about miscarrying. My period was supposed to be here 3 weeks ago the 5th of December but it never showed. My last menstrual was November 8th. Do you think I’m miscarrying or do you think it can be my last period ??? What are you guys thoughts !!
