31wks and feeling sick

Cougar

Hey yall, I’m wondering if I maybe have a bug or something. Ever since I woke up this morning I’ve been crampy, my back is achy, I’ve had the poops (tmi I’m sorry, but not diarrhea) and now I’m lightheaded despite having eaten just a little bit ago. I have POTS and I tend to faint, but haven’t since around 12wks as it’s gone into remission with the increased blood volume of pregnancy. Anyways I’m wondering if it just sounds like I have a little stomach bug or if y’all have gone through this.
