Getting worried about being a mum now it's all becoming real

Anyone else starting to freak out and question themselves now it's getting so close? I'm a first time mum at 36 weeks with a planned pregnancy (although I have to admit I thought it would take a lot longer to conceive than it did) and I'm really starting to stress and get worried that maybe we weren't ready for kids after all, what if I'm a bad mother, what is going to happen to the relationship between my husband and I... Anyone else getting cold feet? I just can't wait to give birth and have the hormones kick in as I know as soon as I see my baby all this will go away but in the meantime I'm freaking out and can't seem to stop :(
