I'm due my period Friday and I've taken negative tests so far (I know it's too early but it got the best of me!) I've not had any signs that my AF is coming such as bad cramping and brown discharge (this is my usual symptoms of AF 3 days prior, sorry for TMI) however I've had bad back ache, nausea spells, headaches nearly all the time! Which I never usually suffer from. But obviously I am symptom spotting. This morning when I wiped I had this CM? Anybody know if this is a sign or is normal at this point? Thank you!! And yes TMI warning!
