Benzonatate affect fertility?

Curious if anyone has been in my situation. I’ve had a cough for 7 weeks so I finally decided to see my doctor to see whats up. I mentioned to her that we’re TTC and she prescribed benzonatate for 10 days. I’ve tried googling but can’t really get a straight answer on whether it will affect my fertility or not. I suppose I could call the pharmacy and ask but thought I’d reach out to you all first. I’m kinda freaking out because I’m in my fertile window and super anxious to get pregnant cause ya girl isn’t getting any younger. This would be my 2nd and I really want my son to have a sibling! Any advice is appreciated! ❤️
