I am 25 wks pregnant and I am having what feels like a sinking feelling in my abdomen. Reminds me of an anxiety attack, but its alot lower then my chest. It feels like my womb is literally sinking. Also, I am having more and more frequent and stronger sensations in what feels like my cervix. This is my 3rd child and I haven t came across any of these symptoms before. I am 28 yrs old, 61in, 118lbs.
