So I'm on BC (Tri-previfem) and I missed a few pills right around ovulation and DH and I had unprotected sex pretty much everyday I was fertile. About a week and a half before my expected AF I started spotting. TMI warning: It's only when I wipe and the first day it was really dark brown almost black and now its been dark-light brown. I've been wearing panty liners but it's kind of pointless because it literally only gets like 2 smallll spots IF that.. I don't want to get myself excited with the thought of being preg but I want to know if this is possibly IB? I took a test 2 days after spotting started and got a BFN. I'm trying to hold out on taking another test until I miss AF (expected by feb 10-11). My last Pd was 1/15 and I started spotting on 1/30 and have been ever since. This has NEVER happened to me in my 10yrs of having my pd and 4months of taking BC... Help me out Ladies/Mommies.. Am I possibly pregnant?
