@jessy I get really bad migraines, that is MUCH worse now that I'm pregnant. My doctor says it's somewhat normal. (but I also have a history of migraines)
My doctor suggested that I drink extra water, sometimes dehydration can make headaches worse. and get a really good night's sleep.
If it keeps going, head to the ER. They'll be able to give you something that won't harm the baby and will make you feel much better.
I hope this helps a bit!
