Blood loss after birth?

After I had my 2 year old in October 2019, I remember them saying I bled a lot so they kept me on Pitocin and gave me a shot in my leg of some sort. I believe they kept me on Pitocin to help with that and all ended up being fine. Now that I’m pregnant again im being crazy paranoid it’ll happen again but worse! Like how do they save you from that? lol Anyone have any stories to help me feel better. Also I’m on baby #5 and my last baby, and I ALWYAS get the epidural. It seems to really relax me and babies usually come just a short few hours later
