Congratulations Nics17!
I am in the same position as you, except I am 44 and this will be my first baby.
My options are midwife led home birth or hospital and I am still undecided at 29 weeks.
My only advice is that, at 12 weeks, you have ages before you have to make a decision so plenty of time to talk to people and research risks.
My midwife is happy to support a homebirth and I have met a consultant who said she would prefer it if I chose the hospital option but it is up to me. She also said that, even as a 1st time Mum, my risks as a fit and healthy 44 year old with an uncomplicated pregnancy are far less than, for example, an obese 25 year old who smokes (her example).
It has always been common for women over 40 to give birth (might want to do some research there sycamore
). It is women having their 1st baby over 40 that is a more recent trend.
As far as I understand it, rather than age, the strongest indicator of potential risk is how previous births have gone. You have already had one successful pregnancy so, statistically, your risk level will be significantly lower.
It is likely that you will not be able to use an MLU purely because of age protocol (rather than any risk specific to you as an individual) but a home birth may be an option. Or, as a PP has said, your hospital may have a pool.
I sympathise, as it is hard to weigh up the risks and you will get loads of advice from people with completely opposing positions!
On the positive side, one little perk of being officially a geriatric mother is that you will get extra scans as you progress, which is lovely and reassuring.
Good luck with it all!
