live alone with my baby or prolong that for 6 months to live with my sister ?

♡ 𝓚𝓪𝓽𝓻𝓲𝓷𝓪 𝓵𝓸𝓾𝓲𝓼𝓮 ♡
I'm 38 weeks pregnant , due in 10 days and I did fly back from America to the UK to getaway from my horrible husband so I'll basically be a single mum. I have everything for the baby so we are waiting for me to go into labour. 
Because I'm unemployed , when the baby is here .. with me being a single mum I am eligible to have a house for myself with the help of the government which is just what I wanted and really need.
Where I live atm is a nice little town I've lived in for years and I have friends here and I just generally know and like the area.
My sister and her fiancé , who I'm temporarily living with until the baby is born ( as planned ) are looking into renting out a 3 bed house ( for some reason ) near her boyfriends work which is half an hour away in an awkward town. She asked if I want to live with them for 6 months so I can MAYBE get my own place over here but I don't feel like I want to.
It will be more stressful to move twice, with a new born to live with them somewhere new for 6 months. Personally I'd rather get my own place as planned and start collecting my own furniture and such , for me it seems pointless to prolong it. I asked my younger sister what I should do and she said I should stay and get my own place because all my older sister sees me as is a maid.... which is true... all I do is clean up after myself and those two , which is stressful enough and that's without the baby being here ! Then the sister I live with always moans about my cat scratching a little bit at their door in the morning, so this all makes no sense.
They are also getting married on July so it would be more weird to still be living with them then with a baby, I already feel weird saying I love with her now. I wanna be independent. I explained if I ever moved to live with her I can't afford rent and she said that's fine but still, I generally feel like it's more right for me to try start 2017 on my own with my baby.
Plus, they haven't really spent proper time together because I've always either lived with them or my younger sister has visited for a while. It would be interesting to see how they are with each other on a daily basis with no guests or room mates around to speak to so they have to interact with each other more, 
Am I right with my decision to live by myself ? Don't see the point prolonging it , with the chance the government might not help me in 6 months time to get a house.
