alright ladies. im supposed to have a visit from AF this week and i feel like im flooded witb excess CM. Ive never had this much CM before a visit before. last month i was hoping for a bfp but with marital issues coming up im not sure anymore but this CM has me wondering. Im also having strange headaches that are making me dizzy and nauseous. i know with my first i had a lot of CM the first few weeks as my plug developed. Any seasoned mommas with some pre pregnancy knowledge that can shed some light?
