TTC TikTok Question about Mucinex

We have been TTC since our miscarriage around the 4th of July with no luck. I randomly came across a post on TikTok that says taking Mucinex has helped lots of ladies conceive, it loosens all of your mucus and I’m assuming just helps out.. down there?! Have any of you ladies tried this. I did a little research and it says it’s not bad for you but also not true. I did take a dose yesterday and today bc I am at peak fertility today if I can get my man to give in and give me some haha but just wondering if any ladies have had any luck with this?! I am to the point of trying anything..
