Ok ladies need some input. Though I started my period yesterday 12-13dpo (2 apps, ff is 1 day ahead of glow), I had pink when wiping in am then it turned brown then had a little red after bm (from vagina 100%) used a tampon and when removed some brown but not much then by the end of the night nothing except brown only when checking cp. I expected temp to tank today but it went up slightly so I took an hpt and bfn. I'm a poas addict so I used an opk after 5+ hr hold and blatantly positive so dipped hpt in same urine and bfn. Today small amounts of brown cm when checking only. What is going on????
