Weird discharge

Now that I have your attention I just need to know if I'm the only one going through this. I do have a doctors appointment coming up tho. So I stopped my BC in October had withdrawal in November. No sign of AF. I've spotted here and there. Especially brown discharge. I was all eww and wth. Anyways. Sunday I had brown discharge and it was enough to stain my panties. Woke up in the am gone. But later on during the day it came back. Same thing the next day. And the next day. Nothing in the am but when I go about my day oh hey how ya doing. To the point I have to use a tampon to collect it. So im like ok this is my period? My bbt has been the same temp as well these past 4 days.

Today my opk has gotten a little darker.

No odor is coming from the discharge. Its light. And the tampon would have some pink/red to it. And sometimes clots but super tiny. And it cant be pregnancy because well I took a test and it was negative.

Unless Im testing to early or Im blind. Or the fun part im testing and my hcg levels are just way too strong haha.

Any of you ladies can relate?
