Hello ladies, i'm after some advice. Today and yesterday i've been feeling pressure down low whenever I'm sitting down with a straight back, if I sit with slouching its not too bad. Also when i'm walking around it feels like I have my period pains back as they are low crampy pains. I'm worried as my cervix was measured at 2.2cm so a bit on the short side, is this something I should ring my midwife about? don't want to ring incase its perfectly normal, its my 1st so no idea what's right and wrong. 19+0.
