In my experience if you are at your job less than a year before being 25 weeks pregnant, you are only entitled to statuatory maternity pay (which is usually six weeks at 90% of your pay, with a further 26 weeks SMP (which I think is £123 a week) and as is the law here (I believe, I am no expert) they have to hold your job or a similar job for a year. But (I know this is the case at my company) if you are at your job for over 52 weeks at your 25th week of pregnancy, you may be entitled for more maternity benefits. Because of your relative newness at the job, you might not be entitled to their full benefits. Best to check your contract, all that info should be in there. Good luck! (again, I am no expert, this is just what I believe is true and I think is true for me at my company)
