You will get through it.
I am not saying it's going to be something you'll not be traumatised by, but you will be ok. You have three beautiful other children as well as this one and they will help you through it.
My cats helped me with mine - sounds silly but it's true. It feels like you'll never cope but you are obviously such a strong person, you'll come through the other side.
My mc changed me as a person. I didn't want it to happen and would never obviously want it to happen again, but I think I learnt a lot about myself on reflection. Not the way I wanted to learn new things about myself, but I will never ever forget my first baby. Whatever anyone says, it was a baby and it was ours.
Again, on reflection, I am so glad that I took the time off work that I needed. It helped me to grieve and the MA volunteers were just superb. I had so many questions.
Take the time to grieve and have time out from the outside world if you need to do so.
Other than that, yes, make sure you have pads, even when you think you don't need them anymore.
Try to get some sleep tonight.
Still thinking of you. Xxxx
