I didn't want it and wasn't going to take it, but my 3rd stage was a bit long (actually about 7 minutes before the injection, about 5 more afterwards, not long in real life, just long if your used to medically managed 3rd stages, which my midwives were) and my midwives looked worried. DD was a bit blue at her 5 min APGAR (scores 9 at 1min, 7 at 5min, 10 at 10min) and i wanted them to focus on her and not worry about me so i let them give me it. My placenta came out when DD was pink and breathing well (before she was interested in feeding though) so i think my body was just tuned into her, despite the cut cord, and waited until she was fine before ending life support iykwim.

As an aside, my worried midwife began cord traction when i declined the synto 1st time. I was more worried about my quiet bubs but i remember wishing she'd stop, that was another reason i took it - i felt the synto gave less risk to me than cord traction. I also should say that i'd hoped to avoid the synto because i wanted a natural birth but by then i'd already used the gas and air so i was a little bit "what the hell" about it. LOL.
