i have terrible allergies, every day i am miserable with having to blow my nose every five seconds. i just need some relief, i completely stopped taking my allergy medication ( Zyrtec or Claritin ) because i am 10 weeks pregnant , i was wondering if it is safe for me to start taking it again, since it's not a take it as you need it drug it's a drug i would need to take everyday, will it harm the baby ?
