Those with toddlers/older babies

I’m going to ask my midwife today at my 30 week appointment but wanted to get others thoughts. If you have an older toddler or baby that you stay home with, are you still as active/involved in play as you were not pregnant? I don’t know if that makes sense lol but I’m still doing swim lessons, gymnastics class, we went to a play place this morning for 3 hours so I was going down slides, crawling through tunnels, climbing ramps etc. And basically doing all the same stuff with my 2 year old and my husband is UP my butt to slow the eff down. Today is actually the first time I feel like I did too much at the play place, I’m exhausted and my back is super sore now. Should I slow down? I feel like if you do something pre pregnancy you should be able to do it during too (for the most part) like I’m still lifting and carrying my 30 lb 2 year old around just as much. I dunno 🤷🏻‍♀️🤷🏻‍♀️ thoughts? My pregnancy has been relatively easy and uncomplicated too.
