Toilet paper dyring pregnancy HELP!!!

Madz • Due nov 9 #first baby
Since ive been 25weeks pregnant I had this crave to eat toilet roll obviously clean one . But only tear two sheets off and swollow it .. sometimes I would chew it and spit it in the bin .. that crave went away after a while but since ive been 33weeks pregnant .. its come back again .. ive been told its pika ive been docs they said uour not anemic or anything ur blood results are fine .. suggestions anyone ???? Will it cause harm to my baby I also take prenatal vitamins .. with that I open my bowels regularly so it shouldnt be a problem to the baby right? Because all the waste in my body is cleaned out 2/3times a day... sorry for TMI but please help girls!!!!!!
