Try not to jump ahead to worrying about hospital. I went into hospy for IV antibiotics when DD was 3 weeks old - not only did they find a single room so I could keep her in there with me, they also let DH stay with me the entire time (it was a post CS wound infection so I wasn't very mobile at that point). You will be ok.

In the meantime, I hope it goes well with your GP - fingers crossed it's just a course of ABs to get it right.
