Hi my doctor just recently told me that I had pica because I had the urge to sniff bleach and eat ice just about all day every day I'm now 36 weeks pregnant and didn't get this urge intill I was about 32 weeks pregnant I go to all my doctor appointments and my baby is at her normal weight and her heart beat is normal the doctor says she's growing like she's suppose to and that she's healthy but I still sniff the bleach and eat the ice everyday and just about all day sense most of the day I'm sleeping or working I was wondering am I hurting my baby still she has all her fingers and toes looking at the ultra sound what other effects can I cause her and is it too late to stop

Sniffing bleach is definitely not healthy.
Ice is just water, so that would be fine.
You should stop sniffing and maybe try to eat healthier and make sure you get all the nutrients you need.
