Potty training while pregnant

Anyone else potty training a toddler while pregnant? Currently 33+3 weeks pregnant and first child is almost 3 years-he’s always been my sweet little snuggle bug but starting to turn into a sour patch kid the closer we get to 3. I’m starting to get really emotional and obviously more uncomfortable the more pregnant I get-just having a hard time in general. Anyone else? Any tips to stay sane during the ridiculous heat and last weeks of pregnancy?
