Does this sound like a normal comment from my girlfriend?

Copied from Facebook chat:-

Me: does Wednesday and Thursday night sound ok [to sleep over] now that you're not here tomorrow? I rather not tie my bro's spare bed up for more than 3 nights if I can help it. I know he likes to have friends stop over a lot!

My GF: To be honest im not even sure I'll be around thursday sorry. Also Im still not feeling great so could do without 2 nights naff sleep in a row

I think the 2 nights naff sleep are in reference to us sharing a single bed but, even so, would you be happy with this response? Should I be worried? We've been dating just over two and a half months.

Sounds pretty normal to me. I think maybe she's either

a) uncomfortable but doesn't want to admit
b) she's honestly really busy and still sick like she said
c) she doesn't want to

If I were your girlfriend I'd expect you to be concerned about the fact that "I'm still not feeling great" - has she been ill or out of sorts lately? Show concern about her health and try to do what's best for her.

Whether or not it's a normal comment, yes it sounds normal enough to me - we girls can get pretty grumpy at times, and remember that the written word in social media rarely conveys the emotion behind it.
