migraines and neck pain

Marifer

so about a month ago i started getting ugly neck pains that go up my head & gives me migraines accompanied with bad bad vomiting .. i went to the hospital when i couldn’t take it & they prescribed me some tylenol with codeine, btw i’m 14 weeks pregnant. i’ve only taken one pill ever since because i’m just so scared that even if the doctor said they’re safe that they might not be.. am i over thinking? the headaches are pretty bad 😔
