Placenta

Ashley🌹🌹🌺 • I'm a FTM with experience of babies from raising my sister. I'm an herbal nut who's madly in love with my soulmate.
I'm a FTM, and was wondering how long should the placenta pump blood before detaching it? I've seen comments about 2 minutes all the way up to 4 hours. My husband and I have been discussing it but don't have a reference on this subject since neither of us know anyone who's left it attached for any length of time.
