Kind of curious... so I am almost 7 weeks although I did have implantation bleeding about 1 week prior, so it could be 8. This is my third pregnancy and my uterus is already about 2 inches out of my pelvis. I have also been woken up every night the passed week just to pee. Plus I have had more nausea than normal with vomiting. I have never had that! Could this be twins??? 😐or is this due to my previous pregnancies? 😊
