Clomid and mucinex

Ariana🐧🌌
When did you start taking mucinex? I did make sure to get the pack with the g-word as the only active ingredient. I want to start on my last Clomid pill (cd 9) but last cycle I didn't o until CD 17 (usually I o on cd 14-15) and I read you should only take it a week before you o. Any tips would be super appreciated. I'm trying not to hit 5 years of ttc 😂😂😂😂
