Need positive thoughts

I’m currently about 7 weeks pregnant. I started bleeding Thursday and got an ultrasound and the baby is doing fine. Bleeding ended by around Saturday. Today I woke up with less sensitive breasts and I saw a bit of brown mucus when I wiped tonight after peeing. I wouldn’t think anything of this but I had a miscarriage in August and experienced similar mucus. Anyone experience anything similar? I haven’t had anymore mucus and my breasts kinda hurt, but much less than the last few days. Is it common for your breasts to become less sore? I know that’s a sign of a miscarriage, so it’s killing me. I have my 8 week appointment Monday so I’ll get confirmation then, but until then I’m probably going to stress 😞
