Hey bubno.3 yea i've had cramps on and off in my tummy which I thought were braxton Hicks, only the occassional one here n there. My lower back is quite achy, just these weird throbby, achey pains in my cervix that i'm not sure about. Should I call my Ob? I thought maybe it could be a normal part of 3rd tri, and being my first I don't have any experience, unsure what's normal and what's not.
