Me too and i'm 16 1/2 weeks. I asked my doctor and he showed me a diagram and said that when we were in our moms connected by the umbilical cord there was tissue protecting it. Well, that tissue goes down to the pubic line and now that we're pregant it's stretching along with the uterus. Weird, but that's how he explained it. I guess it's the first time it stretches also. So, he said when it hurts to change positions and if it gets bad take tylenol.
I hope this helps.

Thanks hun that helps lots!
