9 weeks pregnant and tight muscles!

[Lollyv]

Hi everyone,

I'm 9 weeks pregnant and for the last few days the muscles under my belly button have been feeling very tight to the point that standing straight gets quite uncomfortable! It's almost as if someone has shoved a balloon in there as it feels very tight.
At 9 weeks this seems a bit unusual from what I've been reading but has anyone else experienced this and knows why?

Yes! I felt like I'd been doing sit-ups. It's just the uterus growing and everything adjusting.

According to my experience muscles tightening may start early in your first trimester as your uterus grows. As your pregnancy progresses, it may be a sign of a possible miscarriage in the early weeks, premature labor if you aren’t due yet, or impending labor. It can also be normal contractions that don’t progress to labor.

I had this from about 5 weeks. Definitely normal

It's your belly expanding :0)
