Brown spotting at 4 weeks 4-5 days

Hi everyone! This is technically my third pregnancy, but I’m praying that this one sticks. I’ve recently started spotting brown. I don’t have any cramps really, and sore boobs have been on and off since the TWW.

I need hope. Has anyone had brown spotting this early and everything was ok? I had a chemical pregnancy in November that kind of started this way, except it was mostly red spotting.

Please let me know! Thank you!
