I am 4 weeks 5 days preggo with my 5th child. I have been having cramping in my lower abdoninal. It feels just like pulling sensation and a achy feeling. The thing is I went yesterday for ultrasound and nothing was seen. So is it possible to have this pain with my 5th child but nothing show up yet???? I am also so incredible bloated I look like 4 months preggo. Is this common cause I do not member ever being this hugely bloated this soon. thanks ladies.
