Is milk of magnesia safe ?


I am super constipated. I’ve tried bananas, apple juice, drinking plenty of water today. I can feel that I need to go the bathroom but it just won’t come all the way. I don’t want to strain or hurt myself. So is milk of magnesia safe for us pregnant women? Or what are some laxatives that worked for you ladies? Thank you for the help. This started last night & I just need some relief.
