Is anyone else experiencing this?

Okay, so at first I thought it was because I ate something bad. But the pain isn’t going away.. it comes and goes. It feel like a tummy ache.. can’t really explain better😭 but lord... it doesn’t feel good... I am 28 weeks! Is anyone else experiencing this? Or knows what it is?🙁 I’m a bit worried. Help a first time mom🤗
