Is it creepy to follow a girl in your class on instagram?

Okay, so I am fully aware how much of a loser im gonna sound like in this post, Im just asking u guys to look past that and hear me out. For the past month, I have been getting over a breakup. I have been meeting new people, working out, focusing on school, etc. Recently, I noticed theres a girl in one of my classes who I think is interested in me. We have shared glances, smiles, and I catch her checking me out sometimes since we sit next to each other. However, after class shes always in a rush to leave and this class only meets once a week, so I had no opportunity to actually talk to her. One of my friends has her instagram, but I dont want to follow her without at least talking to her first. However, the semester is almost over and I might miss out on something special if I dont do SOMETHING. Advice? Lol
