Sore tummy at 13 weeks?

Heydie

Is it just me or do some of you feel like you guys have a sore tummy? Especially in the middle of the night after I pee, my stomach just feels heavy and sore but goes away after a few min. Same thing happens when I'm at work and just laying back. I know baby is getting bigger but just wanted input on how your tummy feels at this stage and trimester? Aaaaand it's that time where I'm starting to show a little. Maternity clothes? I think yes! 🤭
