I'm sorry- that sounds like an unhappy experience. And I'm sorry to the OPs too, for going through what they did!
I had a minor PPH - 850mL. Mine wasn't a fast labour- 3cm when synto was started around 9am, didn't push til after 5pm, DS delivered by vacuum at 6:30pm. I had an epidural, which I think was my saving grace, as it reduced the pain. I didn't realise what was going on at the time- just knew that the midwives kept massaging my abdomen (which hurt, despite the epidural) and thought that they were" tugging" the placenta out (which really hurt). It was only later that my husband told me the OB had manually removed it, and that he'd been in "up to his elbow". I also had the suppositories afterwards.
I'm thankful that it was a minor PPH, and can only imagine how scary it must be for women losing lots more blood. I'm also glad I didn't realise at the time what was happening, and that the OB, midwives and DH did such a good job of staying calm and reassuring. I only later realised what had occurred from DH's comments and those of a nurse, who said she was amazed how quickly I was up and showering afterwards.
I was a bit shocked by the realisation, and during those first weeks had a few good cries over it. I think, though, that because I didn't know at the time what was happening and hence wasn't scared, and because it was a smaller PPH, it's been a shorter path for me to come to terms with it. I'm now okay with it.
If you're feeling traumatised, please do speak up and tell someone. It's not something you should keep bottled up, and talking can help you process the grief you feel over the experience.
