Zantac and decreased fetal movement

Jennifer
So, I'm 22+3 and I recently started getting heartburn so bad I was sleeping sitting up just to alleviate the symptoms. My doctor told me to take zantac, but when I take it my daughter moves significantly less and sometimes not at all. She normally moves after meal time because I always have something sweet with breakfast and dinner to make sure she's ok. Has anyone else experienced decreased fetal movement after taking Zantac?
 (Also I'm not going to take it anymore.)
