Maybe a break through period?

Maybe a break through period?

If I didn't feel crazy before, I definitely do know. Every month I ALWAYS get cramps before AF and I get upset stomach every morning. This month I had none of that but last night noticed some pink EWCM which is normal before I start so I counted myself out and put a tampon in. Now nothing but some brown EWCM through out the day and no cramps. I just can't come to grips I'm out. Anyone go through this & get a BFP or a dreadful BFN. I'm going crazy lol
