TMI question

Erin
I have NEVER been a good judge of my CM. I dont understand it. But anyway. Okay. So my fertile week is here, and I also have a cold. I know taking a decongestant can be good for your CM too. So every morning I take my mucinex and get on with my life. The past two days I have had so much CM that I actually thought I started my period at one point during the day. And it's the consistency of snot, that's the best way I can describe it. It's not sticky though, like it doesn't string from finger to finger. I'm so confused. I dont ever remember having CM like this. Is this because I'm taking the mucinex? Is this good baby making CM? I'm so lost. Any advice is appreciative.
