If you push upwards with your fingers or if your pants or undies are pushing right on the hair line it can irrate the uterus. Mine just gets a sharp pain and then goes away.
The normal hair line is a good physical marker as to where the end of the pelvis is, and where the bottom of the uterus begins.
Yesterday I had a lot of pulling and tugging pain going on, then this morning I am showing more than yeserday. I know that pains where from the uterus growing.
What do you mean being pushed on from the bottom? Thats kinda where mine pains are. I thought maybe the baby dropped down or something lol
I get pains right where the hair line begins. She said that is the bottom of my uterus, and it isn't so happy with being pushed on from the bottom. I went in at 13W2D and my uterus was measuring 10cm, and the babies heart rate was 165. His or her heart rate has always been fast, I wernt in at 6 weeks and it was 160, then 168, then 165, and again 165. . . . WOW! I would have a heart attack if my heart rate was that fast 24/7!
I've been having it on and off...I think it is pretty normal as your body changes. Not sure about the uterus...they found mine at 8 weeks.
