Does taking Mucinex really help TTC?

Alexandria • TTC for 4+ years. Got BFP on 6/15/2015 and estimated due date is 2/6/2016!
It's not a cure all, don't take my wording wrong. BUT, I read somewhere about people taking Mucinex to help with cervical mucus and make it less difficult for the spermies travel. Just wondering if anyone here has done this or knows if it really works? 
Sorry if this is a stupid question! I guess I'm just desperate I'll try anything ?
