Or you may not want vaginal examinations at all. I stipulated that WAY before the birth. I birthed in the pool in the front room. I then got out and settled on the sofa to cuddle and feed baby (for nearly two hours), and that's where I birthed the placenta and was checked for tears (none!). I wasn't on the bed for anything. My only toilet and bathroom are upstairs, so after the cord was cut and I'd had a drink, my doula and one midwife came upstairs with me in case I needed help, as I'd passed out after my first birth when I went for a shower, even though I didn't lose much blood at all (midwives also like you to do a wee before they go, which I did). I had a wee, my doula helped me have a quick shower and both helped me into my pyjamas. Then we all went back downstairs.
They can advise all they like, and you can consider and decide whether to accept that advice or recommendation. But no one can tell you that you must or must not do anything in relation to your home, your pregnancy, your birth, your body, or your baby. You're the only one who does the allowing. (And if you're fine with the stairs, that's all that matters - they're actually good as you may find going up and down keeps labour going or that a stubborn placenta may shift after a walk up to the loo.)
