Bleeding at 6 weeks

I’m around 6 weeks pregnant. Yesterday I started to have some pink bleeding that turned brown so I went to Hospital. They scanned me and said it looked small but could clearly see the heart beat and they showed us. They booked a scan for a couple of weeks time.

When I got home in the evening it started to become red and today it’s heavy with little brown bits in it. The blood is stringy when I sit on the toilet (sorry tmi). I’m changing my pad every 2-3 hours or so. I have slight cramps like period pains but nothing extremely painful.

I know I’m probably having a miscarriage. But does anyone else have/had anything similar? This feeling is awful :(
