Pregnancy and exercise. I need help.

I can’t go to a gym because 1 COVID and two have a son already and outside is way to hot and humid for me right now and or it’s pouring rain. I am in desperate need for a workout to follow on youtube or Facebook so I can have consistency! I’m nearing 300lbs and I’m only 26 weeks and have already gained 10lbs. I need to not gain any more weight. I was doing P90X in the first trimester but that was just too much and then summer hit and I can not STAND being hot or sweaty.

Please suggestions for YouTubers or Facebook people/pages to follow for workouts.
