Mucinex

So I have seen on here a few times about taking Mucinex before bd-ing because it helps make it easier for sperm to get to the egg. Today is my high day full on dark 2 lines on my test and probably the only day this fw we will be able to bd...

I am having a LOT of ewcm with your experiences does this actually work?? I’m assuming I’m supposed to take it orally.. also how soon before should I take it?
