i dont understand why this would worry you? people swallow things all the time that aren't food and are just fine.
if you're pregnant it still wont matter.
I'm a hairstylist and I eat/sleep/breath hair. I've had no problems at all.
It should be passed ok...After all the churning in your stomache(if the stomach acid hasnt eroded it) it will be bunched up likely and pass, My daughter (10 months) just passed on of my hairs which was probably 11'' in length. She is fine.
This is a pregnancy forum for questions related to pregnancy. But to answer your question no it isn't a problem it's just gross
