Mrsb - I think it depends on whether you have a midwife to call! I don't really have someone I'd ring about relatively low level things, I've not met a local midwife at all. When I mentioned the pains at my 17 week consultant appointment, he just said 'it happens', and said that if I had other issues, like bleeding, then it was an issue, but otherwise it's just stretching. I don't know about you, but prior to being pregnant, I had a coil and my uterus constantly hurt. I just think I've got a precious darling of a womb, which doesn't like anything anywhere near it, so shouts a lot. I've had a variety of different cramp type pains, more so since I actually started getting bigger, and none of them feel 'wrong' really - just stretchy, even though some have made me sit down pretty quickly.
