Hey ladies, I am curious if any of you feel this from time to time. It's normally only when I'm in bed or getting up in the morning and stretching. When I roll over it feels like my stomach tightens up a lot. Then it goes away. It's almost like a feeling like I'm sucking in really hard but it does it on it's own. When getting up out of bed I also sometimes feel like I need to tighten my stomach muscles. I don't know what this is. I know it isn't round ligament pain and I'm pretty sure it isn't braxton hicks yet. Sometimes it happens when I straighten my legs out to stretch them because they get sore and cramped up just while I lay and sleep.So when I stretch my legs out my stomach will also tighten and sort of "stretch". I'm sorry it's so hard to explain. I will bring it up to my doctor on Wednesday but I just wasn't sure if anybody else felt this tightening sensation and knew what it might be already.
