Watery poop can happen in the first trimester due to hormonal changes and increased progesterone, which affects your digestion, so it's pretty common. That said, if it's persistent or you're feeling unwell, might be good to mention it to your gynae or PD just to rule out anything else like a tummy bug, especially since staying hydrated is important when you're pregnant. Most mums I know found it settled down after the first trimester, but everyone's different.
Yes quite common actually! Hormones during first trimester can mess with ur digestion and cause everything from constipation to the opposite lol. Also if ur taking prenatal vitamins some of them can cause loose stools too. As long as ur not having like super frequent diarrhea or blood in stool should be ok. Just make sure stay hydrated esp if it’s happening often. Mention to ur gynae at next appt just to be safe 😊
