Miscarriage or not?

I’m 6 weeks, 3 days. So yesterday around 11:30 I felt a gush come out of me ran to the bathroom and it was blood, red blood. I freaked out, it kept coming out. Not heavy but not spotting. I called my doctor and said too early to do anything but more than likely a miscarriage. By 3:00 the bleeding had slowed a lot and by 5:00 it was all over. I haven’t bled anymore since, I’ve had some spotting, light brown color here and there. I woke up today with bad morning sickness and tender breasts. So I don’t understand if I’m having a miscarriage or not since I just stopped bleeding? Has this ever happened to anyone?
