This can help me conceive?! Using Mucinex during TTC. Is this kind okay to use?

I know that guaifenesin is the main ingredient people look for in mucinex to thin cervical mucus. Funny enough, I have a nasty cold and have been taking this every four hours for the past day. I looked up the information to see if it could hurt me TTC when actually I read it can help! (1st <a href="">IUI</a> is Monday) I am just curious if anyone knows if the other ingredients will interfere with TTC or our <a href="">IUI</a>. Thanks! 💕
