Help!

I am pretty much bound to sitting most of the day. I have very low iron and just started iron pills to help but I am so dizzy and lightheaded and any kind of upright activity makes it so much worse. I feel like I won’t ever be able to go into labor because I don’t get a lot of exercise or steps in. I cook and do light cleaning, but I can’t get long walks in or anything to help him drop. Is it possible to go into labor without so much walking? That’s how I got my last baby to come.
