Weeks 5-6 spotting

I know several of you guys said you were having spotting on the last post, just wondering if anyone is still having it. My spotting started last Thursday at exactly 5 weeks. I’m now 6 weeks today and still spotting. It’s been very intermittent, sometimes like go hours with nothing, then it will start back again. Well yesterday and today, it seemed to increase in the amount and went from more of light brown to dark brown. Still not enough for even a panty liner. I had my HCG drawn when it started at 5 weeks, which was 9991, then at 5w4d and it went to 28096, which my OB was pleased with. I’m just stressing out still and worrying since it’s increased in the amount the last 2 days and still happening.
