Is something wrong with me?

Hi, I have just started college, and it's going pretty well, all except for one thing. Making friends. I will say that I am a 5'9 woman who is skinny and fairly attractive. I have a set plan for life and know what I want to do and be involved in. I've just been having the hardest time making friends at my college (by the way, it is a PWI). I have gone up to others and started conversations, which led to contacts and trying to keep talking, but it seems like no matter how hard I try, I am nobody's first choice to be invited to hangouts or even a group dinner at the dining hall. I am putting effort into these friendships but am getting little in return. Another sad fact is that it has been a month since I started school, and nobody has approached me at all, except for once when I was eating lunch with some girls I had met, and another girl who was close by said I had a pretty smile. Other than that, nobody has approached me first to even be friends or to strike up a conversation. I am smiling more, walking around off my phone and even down to my hair, just trying to look approachable, but still nothing. At this point, is something wrong with me? I have cried, not knowing why I can't seem to make friends, and it saddened me today when my mom asked about my friends and if I've been making any. Again, is it me?
