Parent guilt

So...I just found out I'm pregnant with baby number 2. Definitely unplanned and a surprise and I have a toddler who's going to be 2 next month. I'm about 7 weeks and definitely dealing with some bad morning sickness which I also had with my first. I'm having some parent guilt however because I can't bring myself to be as active as I was and I can't deny that's he's been having alot of screen time ( educational ) but alot none the less and I was so strict on it before. But I'm exhausted and sick and not sure what else to do when I'm constantly running to the bathroom or feeling like I'm going to 🤢 all the time. I'm not sure what to do, his dad ( my husband ) works and we don't have alot of outside support .😩
