What Should I Do About My Baby’s Movements Feeling Unusual While In The Habit Of Eating Chalk Daily At 32 Weeks Of Pregnancy?

Hi, please I m 32weeks pregnant and eating chalk each and everyday as I m a teacher and always come into contact with chalks. And the kicking of my baby doesn t seem right but when I went for the scan they told me my baby is ok but I don t believe them as the kicking of my baby feels like just a rumbling in the stomach. And I know I m consuming too much chalk which is not right and I don t also take my medication. Please what do I do because I don t want anything to happen to me and my baby
