hello!! welcome to tri 3 where all the fun really begins lol.
I went on maternity leave on the 6th dec and my due date is the 24th jan. so I had 2 weeks of annual leave to take, so up til xmas is annual leave, then about 3 weeks til due date from then, so all in all i left about 5 weeks before! its up to you really on how you are feeling, i feel fine and probably could have worked more to be honest, but i had to take the holiday before new year so i did and thought sod it im not coming back for a couple of weeks to then go on leave, so did it in one big hit!
If you think youll be ok, you might be. i can still be on my feet a lot, but this might change soon. just dont know. lol x
