I planned a homebirth. I was fit and healthy, had a perfect pregnancy and was v prepared. I was active, upright, mobile and used hypnobirthing techniques for 31hrs. I pushed for 8hrs. I was rushed to hospital for an emcs.
I ended up with ptsd and pnd, not because of the mode of delivery but because of the gap between expectation and reality. I decided on the birth I wanted and laboured in the face of a nagging feeling that something was wrong, indescribable pain which I should have asked for help with (there was a significant problem with my pelvis which I didn't know about and dd was in a really awful, stuck position and it caused pain which my body was screaming at me to listen to but I refused). Looking back, the emcs was the least traumatic bit of the whole thing but the feeling that I'd failed, the transfer to hospital, confusion, regret, guilt etc stemmed from my own inability to understand one sure and certain fact of giving birth: you have no control over the essentials.
You can nudge and encourage and make informed decisions but only with what you're given. If you have an unbirthable baby, if events develop and you need intervention, you can't simply unwish it. You are handed a set of circumstances, you and the baby together and you make decisions based on what's best for you and the baby in that situation.
When I had my second I entered it with a more positive attitude. Instead of seeing the hospital and the theatre as a looming enemy, the route to giving in and failing, I saw it as this wonderful, brilliant, clever place which meant that both dd and I were alive to know each other and it was there waiting in the background should ds and I need help to meet each other too.
I ended up with another emcs (like I said, I didn't know about the problem with my pelvis at the time) but I was laughing and smiling as I went into theatre and smiling when I came out.
I can't give birth. But modern medicine can allow me to be a mother. The only way I would have avoided an emcs was either to not get pregnant in the first place or not survive the labour and delivery of my two babies.
There's probably every chance that you will get your lovely, calm homebirth. But arm yourself with information and decide now what you will do in every eventuality. Because if you do end up with an emcs, then the way you will enjoy it is by knowing you thought it through beforehand and made decisions and felt in control of the birth offered to you. So you can ask for the screen to be lowered, ask for skin to skin still, request that they don't reveal the sex etc. There are options in every scenario and they are YOUR options.
Congratulations. Don't make emcs the enemy. It's a wonderful, lifesaving procedure.
And in the event btw, you'd perform surgery on yourself to make sure your baby is okay. Your focus contracts down entirely.
