1 Day Period?

Amanda

Background: 28, been off BC for about a year. Started actively TTC about six months ago. My cycles have been pretty irregular since going off the BC (anywhere from 36-44 days), so it's been hard to keep track of Ovulation. The last two months they seem to be regulating back to my pre-BC cycles (about 34 days).

Current Situation: Started AF Thursday (7/27). Making this past cycle a 32 day cycle. Flow was relatively heavy for the first day of my period and darker brown then usual for me. Next day, AF is seemingly gone and still nothing today. This morning I had a tiny bit of faint light pink discharge, but nothing typical of AF. Also, having some light vaginal cramping.

Took a test last night, and it was neg.

Should I be concerned?
