Please help!? I’m so confused!

Renee

Hey ladies. Will y’all help!? I don’t understand the up & down on my chart & the spotting I had started as very little & light pink, to dark brown & gooey then to a very light brown. Also anytime we’ve had sex close to when AF is expected, I start during sex but we had sex last night & there was just some light brown discharge. I really don’t want to get my hopes up but please tell me what y’all think?
