Definitely invest in an incline pillow and also incline when you’re on the sofa! Totally understand. Just have to give birth laying on the side because I could not stand laying on my back
Prop yourself up as much as possible with pillows. Or lay on your side
Just take it easy. Not much you can do but to make sure you give your blood time to circulate when you get up. Sit up slowly and when you do, give yourself 5-10 mins to adjust. Also, try to lay on your left side when this happens and don’t lay on your back. Good luck mama!
