BRITISH MUMS ON BENEFITS HELP!

So
I'm nearly 28 weeks pregnant and currently on sick after I was sacked from my job at around 16 weeks cause I told them I was pregnant. I did fight this but didn't win. I went on sick due to bad health and the job centre tried to force me to get a job until I was 29 weeks. Nobody would hire a pregnant lady! So now I'm stuck! I'm entitled to nothing for myself after my sick has ended cause my partner is a high earner. Yes my partner should support us but I like having my own money in my own bank to go out and spend! He pays for everything and I can't pay for anything! I won't even be able to buy my baby a pack of nappies!! I am so fuming that just because my partner earns money I should go without!! The British government disgusts me!! When there's people who claim everything!! So angry!! I have worked since I was 17 and never asked for hand outs until now! And I get rejected for it!
Don't wish to hear any negative comments about this either thank you!
