Need help figuring out my chart...

Britt

So this is what my bbt chart looks like right now. I've had brown spotting (IB??) yesterday afternoon and through the night. Just enough to have when I wipe. I NEVER get this before AF. Now my sleep has been all over the place! Not good nights at all. Was nauseous last night and did not get a good night sleep. My boobs are so sore too! And dizziness.

AF not welcomed on the 23rd..

Anyone think this could be my bfp?
