Carrying low in your third pregnancy

What happened to your body after you carried really low? Did you have any lasting side effects?

I’m carrying very low with my third baby and I’m kinda scared because I’m in a lot of pain, and I don’t know what’s normal a lot of pain, or calling the doctor type of pain because they keep telling me it’s normal to carry low and have pelvic pressure with the third baby because my muscles are weak but I wonder if I should be on bed rest or something because my vagina feels like it’s being pushed out of me. I look at it in the mirror and it looks and feels bulgy and like my babies head is right in between my legs already. Feels like what’s inside is going to fall out!

I can’t lift my own legs to put them up when I relax, I have to grab them by my pants and lift them. I pee a lot in small amounts, I can’t stand for more than a few minutes, and I have a toddler. I think I need a pelvic support belt but they are a lot of money and I can’t afford one.

I’m 30 weeks.. I don’t know how I’m supposed to go much longer.. I can’t even turn over in bed without audibly making ouch noises and can barely manage it. I expect a fast labor!

laying down is painful and no position helps me anymore. Terrified.
