Little to no cervical mucus?

I've noticed from the girls on here that I produce like little to absolute no visible cervical mucus in my underwear. On here I see women with large enough amounts of cervical mucus to check thir fertility but I don't even produce enough to check. I'm on Hydroxizine which is basically like zyrtec (average OTC allergy medicine) on steroids. I take it for my severe eczema breakouts and my allergies. I've read that it could be so drying that it drys up cervical mucus. Has anyone else experienced this?
