Should I ask her out again if she blows me off the first time?

I think it's a good thing she suggested another time. If a girl truly wants to blow a guy off she'll probably make an excuse without "rain-checking".

Personally, that happens to me, there are times when a guy catches me at the wrong time to ask me out. So, I tell them I really can't but let them know that I would like to go but at another day.

I say text her during the week to ask her what day would she be available to "hang out". If she keeps making excuses and keeps postponing. I say, move on!

I will say yes but don't call her text her if she can't take the time to call when she has to cancelled then don't do the same if she blows you off again then don't try a 3rd time
