Hi OP, congratulations on your pregnancy!!
Although you can read stuff online, I prefer having a book to hold (given that my life in lockdown is far too dominated by technology!)
My husband bought me 'The day by day pregnancy book' edited by Dr Maggie Blott (consultant obstetrician) and contributers are various GPs/gynaecologists/psychologists/midwives, so I don't think you could get a more accurate, evidence-based and professional write up tbh. Far more informative than NHS website, if you want more than the basic info that is.
I used the Flo app pre pregnancy which has a pregnancy mode too. It's not the best, but still ok to read. But I prefer reading the book each morning and so does my husband!
