Period or possible miscarriage?

I had my last period May 5th to May 10th. I was predicted to start my period on May 31st. On May 27th I woke up to pee and when I looked in the toilet, there was a lot of blood. I figured my period started early and put on a pad the rest of the day. Throughout the day I did not bleed, just had brown discharge. It is now the end of the 29th and still just brown discharge, no blood. Upon research online, people say it could be an early miscarriage. Me and my boyfriend don’t always use protection so theres always a chance of pregnancy. Has anyone had this happen before? I would go to my gynecologist but she is not seeing patients until June 15th. I’m just not sure what to make of this since I’ve never had this happen before. I find it strange and worrisome.
