Eeeeew sweeping - no I cant do anything that feels remotely like HOUSEWORK, lol...
Thats how i felt too... but my aunty swears by it and shes had 5 kids.

As for the nipple stim, I would start getting a bit crampy but nothing too much. I felt like i was going to pull them off lol

I found long walks were what got me started but once i stopped walking so would they.
