TMI. I CAN'T POOP

Today before my appointment I used the bathroom as normal.... except I couldn't pass my bowl movement (which is abnormal because since being pregnant my movements have become more regular). When I say it hurts I mean IT HURTS, I've taken a hot bath, drank lots of water and also have drank some milk of magnesia (which I projectile vomited not even 45 minutes later). Ladies please, when i go to the bathroom it feels like im gonna have this baby instead of a poo. I need some kind of relief. I'm so miserable because it feels like the movement is just stuck at the end of the tunnel. Sorry for the tmi but I really appreciate any and everything that you guys have to offer for this situation.

Sincerely, one constipated mama.
