Question about medication?

I would go back and talk to the pharmacist again honestly. Even though they know you are pregnant, I would show them the paper that says do not use if pregnant and see if they explain why. Sometimes it's a matter of it can't be used in the first trimester, but it can later on or something. And so they just want you to contact your doctor before taking it just in case. I'm sure you will be fine, but I would just check to make sure. Good luck.
