Congratulations - how very exciting for you!
There are huge advantages bing an 'older' mum. I was 36 when I had my first and am now 40 and wondering about going again.
All the talk of bumps has me a little bit broody DH would need to agree, of course!
My GP was very dismissive of me when we had our confirmatory appointment - no tests etc.. I changed GP.
I had some lovely midwives - and was fit and healthy - my last month was tough, as the weather was hot - I had feet like hobbits!
Only thing I woould do differently is to take 8oomg - 1gram Folate (B6 / Folic acid) and other B vitamins per day, as it's water soluble and can leave the body without being absorbed. Folate is important for a few things:
1 for a healthy development of the baby's spinal cord, and
2 to help your body make blood cells.
Have a chat with your midwives - there are pregnancy miltivitamins and miltiminerals available also now, which I would take, as you need to be in tip top form after the baby is born.
I wouldn't worry too much about tea and coffee - I used to drink raspberry leaf tea in the last two months to tone and strengthen the uterus, and I switched to lemon and hot water, and fennel and ginger teas as well.
Good luck bumpy ladies! I'm so excited for you! ENJOY!
