Thanks, Hannah! As it turns out, I'm not worrying about this problem anymore, because I am now 5 wks pregnant!!! In this previous month, I used Mucinex (extended release) for five days up to ovulation. My mucus was thinning but not very abundant, so I starting using Pre-Seed on the 2-3 days leading up to "o" day. I remember crying the days after I ovulated, because I didn't produce any egg-white cervical mucus, despite my intent efforts. All I could think was "what to do next month to fix this". I even went to the OBGYN the day I was expecting my period to discuss my mucus issues. I wasn't expecting to leave the office with a positive pregnancy test!
So that goes to say that you CAN GET PREGNANT without the egg-white quality mucus. It appears that using Mucinex with Pre-Seed was just the ticket to make my cervix a sperm-friendly environment!!!
