Not sure if I'm having a MC

I went in for an ultrasound last night and everything looked as it should for 5 weeks 4 days. Today, I woke up and I had brown red blood, so I went to the bathroom and it took a few wipes to clean up. But that was two hours ago I have barely bled since. I have no cramping and my boobs still hurt. I had a MC before and it started with a little red blood and got heavier within the next two hours and the cramps were terrible.
