Since last night I've been having a full, heavy feeling - almost like pressure - at the bottom of my uterus/top of my pelvis. It's a little unnerving. For those of have been pregnant before - almost feels like that heavy feeling when the baby has dropped or when your waters have broken. Can anyone relate, or has anyone been having this? I'm wondering what it could be... I'm hoping it's nothing scary like my cervix dilating, although that has crossed my mind. I had my 17/18 week apt last week and my cervix was fine...and I haven't had any leaking or spotting (and hope I don't have). But what could this feeling be about? It's very uncomfortable - physically and emotionally.
