23 month old pooping ALOT all of a sudden

My baby will be 2 next month. She has always pooped maybe every 1-3 days. Usually every other day at least. The past 2 weeks it’s been 3-6 times A DAY. The consistency of it changes. One time it’ll be hard, the next it’ll be green and runny and the next it’ll be so dark green it’s almost black. She has no fever, her diet didn’t change at all. Her pediatrician retired a few months ago and since then we’ve been traveling so it’s been hard to find a doctor to see her. The state we are in, does not take her insurance, only the ER does. So until we are back in our home state, it’s hard. Is this worth taking her to the er? She’s not in pain. She also drinks quite a bit and I mix all her drinks with water so she’s hydrated since she hates water alone. I can’t figure out why she’s pooping so much. It’s also causing a lot of rashes which isn’t fun 😩
