Question about baby position

A
I had posted a few days ago about a lot of cramping, I took milk of magnesium and felt better. Now that it's out of my system I feel the cramping again, like bathroom cramping issues not contractions it doesnt feel like it could be harming me or the baby. I am going to the bathroom fine and I can feel the baby moving. I am 21w 3d, has anyone had this experience? Could the baby be laying on my intestines? I have a regular check Friday morning and was going to ask my doctor then.
