ttc need advice!!

Katie • No children, 5 MC, Trying for our rainbow baby 🌈
Hey all, just need some advice! I've had a few miscarriages in the past one was early this year but I've just started a new job and it involves laser, I really want to start trying I don't want to wait any longer watching my friends  having babies gets me really upset and I'm thinking why should I wait?! So as my new job has a probation period of 6 months and I'm only on my 6th week and it's only a small business I get on with everyone so well but I'm scared they will get rid of me and use an excuse that they don't need me? If that happens would I be entitled to any help if that did happen or if I left later down the line?
