It's definitely normal to feel a little unsure, the "norm" is to give birth in hospital and not everyone is supportive of home birth.. I find that doctors are usually dead against it whereas midwives are all for it!
I had a home birth planned with my third baby but unfortunately it couldn't happen in the end.. My waters broke and after 24 hours I still hadn't gone into labour, and NHS policy is to induce after that long. I'm not saying this to put you off or worry you, but sometimes things don't go to plan and I think it's important to be aware of what can happen. I had my heart set on giving birth at home; a hospital birth wasn't in my mind at all, and I felt so sad afterwards when it couldn't happen. No-one understood why I was so upset because "all that matters is having a healthy baby". Of course I knew that, but I still felt sad about it. This time I'm still planning on a home birth and I've got everything I need for it, but I'll be preparing for a hospital birth too.
Saying that, the majority of home births in the UK are successful and don't require hospital transfer so I think my situation was particularly unlucky. It's a very safe way to give birth providing you're low risk, and it seems like such a calm, wonderful way to bring a baby into the world!
One of the things that appeals to me about home birth is having my own space afterwards. I've been on a shared postnatal ward 3 times before so I know what a luxury it will be to have my own bathroom and bed!! And family visits can be on your own terms - you can have your family round to meet the new addition as soon as you're ready, without visiting hours or restrictions.
It's also important to me to not be away from my older children for too long. I don't want them to be there for the birth but I want them to meet their baby brother/sister as soon as everything's cleaned up and we're settled into bed.
I recommend watching some home birth videos on YouTube if you're still feeling unsure about it. Some are really amazing and usually make me cry!
All the best.. I hope you get the birth you want
