@cubanqueen, MIGHT be your only option Mama. Since you're pregnant, I'm not sure what's safe and what's not. I DO know how fucking MISERABLE constipation is. I'm SO sorry girl, I hope you can find some relief.
My doc told me to use Myralax (not sure if I'm spellin it right) when pregnant and it worked great. I could mix it with any liquid I was drinkin and it wasn't weird, chalky or funny tastin at all.
@cubanqueen, dulcolax brand actually has but any brand will do , or a liquid enema both are inserted rectally - sup is a solid little thing you insert and wait a while — enema is liquid the urge to pop is almost instant ! Make sure you are very close to the bathroom
