When should you stop laying on your back?

Cara

Clueless 2nd time mom here - I forget everything, it’s like I’ve never been pregnant before. 🤣 When should I stop laying on my back? Or should I say: when is it no longer a safe position to lay? I’m almost 12 weeks along and it’s starting to get uncomfortable to lay on my back. I get this uneasy feeling in my stomach and a slight dizzy feeling. I remember this happening with my first, but I feel as though it happened later. Like I said, can’t remember shit. I have a 1 year old now and I’m as scatter brained as ever. 🤪
