thanks to all of you for advice im going to doctors today :) xx
It's called Pica. As the other ladies informed you call your doctor inform them. Also inform a close friend who can help lead you away from it. It's common in some pregnancies but it just may mean your body is lacking iron.
Agree with both above ^^^ If you absolutely "need" the chalk before you can get in to see ur doctor, try eating tums instead. The plain kind has that "chalky" taste/texture.
Call your Dr. asap and stop eating chalk! There is a disorder called pica that will make you eat non food but it can be bad for you and baby. You need to let your Dr. know and they will figure out what vit. You are missing
You should stop eating the chalk and talk to your doctor. There is something that makes you crave nonfood items but you shouldn't actually ingest them. Definitely call your Dr.
