23+4 not feeling right

I'm almost through the second trimester with my second baby but I just don't feel right. I've been having pains all over my belly that come and go. I know it's not a (sorry if tmi but it's necessary lol) potty issue because I've gone normally. I can't stand any sort of pressure on my belly at all. There's enough there as it is. My son has always decided to ride low in my hips so I'm pretty used to having pressure there, but not all over my belly. Of course it's Sunday so calling my doc isn't an option but I also don't know if it's just something normal for a second pregnancy. I didn't have this problem the first time around. I just generally feel off and can't figure out what it is or what to do to relieve it. Any ideas and suggestions are welcome. And yes, if I don't feel any better soon, I will contact the labor and delivery nurse for an opinion.
