5 weeks ago I had my 5th baby and iv never been to any antenatal classes just my checkups with the midwife. There are loads of sites you can visit that tell you everything you need to know. I even had apps for my phone I was constantly glued to them. I kind of miss them now too. There's baby gaga, what to expect, baby centre and loads more. If you type in the search bar how many weeks pregnant you are it brings loads up. I hope this has been helpful and good luck and congrats I hope all goes really well for you.
