Pelvic pain during pregnancy?

how many of you guys had pain in your pelvic bone during pregnancy and how far along were you when it started?

it came and went the whole time
it's just yours bone moving apart so you can pop that baby out through a bigger hole

I started having it when I was 5 months along and it lasted until the 8th month. The 7th month was the most painful for me, but I was carrying a 7lb. 7ozs. baby, and I am only 5ft. tall. I didn't seem to experience it with my other two children, just my first.
i had it at about 3 months but i also had twins, i would go see a doctor asap
with my first it started in the 7nth month, with my 2nd it was the 5th month. it's just the bones loosening up to prepare for delivery, don't be worried.
that is a very common complaint at least that is what my doc told me when i had my son that is after i was three months and miscarriages were less likely.
Oh man did I! I don't remember exactly how far along I was but I know I had it the whole pregnancy on and off. See you OB.
I was about five month when it stated and lasted all the way up to the end.
