Roommate problem, am I in the wrong?

Okay so I'm having some roommate problems and I'd like some advice. We've been roommates for three years and we're pretty close, we both have a lot of stuff going on and are graduating on the 18th, we have to move out by the 17th, and I'm currently almost 7 months pregnant. Recently, she had a huge falling out with our other two roommates and I took her side because honestly they were being really two-faced. So as of last week we do not really talk to them unless it's something involving all of us. This past weekend I was working on a really big final project and I work from about 3-11 PM, IF people leave the restaurant on time, which anyone who works food service knows rarely happens. It was a long weekend, I haven't been sleeping well lately because pegnart, and we've been training a new person at work, plus the boss that I love is quitting and the new boss is awful and openly resents me for being pregnant. So all in all, it was a really rough weekend. Sunday night (big project due first thing Monday morning as well as a test) and she texted me to let me know her flight back in would be delayed and asked me to stay up and track her uber home. Obviously I said of course I would. I luckily got home around 1135, and at about 1145 she texted me and said Lyft wasn't taking her cards. I asked if she had tried uber and all she had to say was that she deleted her uber account a while ago. I told her she could probably get a free ride if i sent her my promo code and she signed back up, then she got all pissy and said "it's fine. I'll figure it out". At NO point did she ask me to come pick her up. If she had asked when she found out she was going to he delayed I would've just driven to the airport straight after work, but she didn't and I didn't think to offer because I was busy working. So now she hasn't spoken to me since then. Am I in the wrong?
