Squats

I dont think you will ever find an answer to this question because everyone is at a different spot in their exercise journey. Also, it's going to depend on the day, you will have some good days and some bad days.
Ina May Gaskin (if you know who she is) recommended 300/day. Not all at once, spread out throughout the day. Many people say that's too much. Some say 3 sets of 10 or 15, others say 25, others say 100. 🤷 Do what you can and most importantly listen to your body. If it hurts, stop.

Remember you should not do squats if you are at risk of early labor, have vasa previa, or the baby is breech at 30+ weeks.
