Migraines

Okay so I'm 14w6d and since I've been pregnant I've taken four tylenols a day for my migraine. And by the end of the month I need to buy a new pack of like 120 because I take four a day for my migraine and it does nothing. I've looked up cbd and I'm going to ask my doc but has anyone tried it or can point me into another direction. I'm sure 120 pills a month isn't good for my liver and I'd like to still have one by the end of my 9 months. Thanks !
