Mucinex and Evening Primrose Oil?

Ashley • TTC #2 , Military Wife
Has anyone used Mucinex in combination with Evening Primrose Oil prior and during their fertile week to thin out cervical mucous and help aid in becoming pregnant? Did it work? I started last night as I'm 5 days before what Glow shows as my fertile week. We've been TTC for 7 months now and have a healthy sex life so hoping this may help. Just wanted to see if any other women have success stories. I know the recommended dose is 1200 mg daily.
