16 hours after my c/s a dr came in and said I needed an injection to stop blood clots, but my midwife was there at the time and said no thats not routine anymore and I didn't have it (drs choice, it wouldn't have bothered me either way). I was up having a shower half an hour later and midwife just said do leg exercises, move toes and promote blood flow, and keep moving around a bit to prevent any clots.
