not sure you would get income support with your husband working but you could look into it, maybe they would give you small amount. You will get child tax credit (about �45-�60 a week depending on age of child, they get more under the age of 1), child benifit (mine is �17.50, although you get more when they younger) your partner will also be able to claim for working tax credits. also there is a scheme called healthy start, you get milk tokens that can be used for milk and veg, you should apply for that whilst pregnant as well as they can be used now for your self. If you want any links let me know i have most of them, or ring citezens advice and they will tell you everything you can have.
ps not sure if you will be able to get a sure start maternity grant �500 but its worth looking into.
