How to make female friends

I, f(19) have never struggled with this before . From early childhood I've always had girls as close friends, and even at my previous uni I had plenty of girl friends. But at my new uni I'm struggling to make female friends, (I'm specifying females because I already have a decent number of guy friends which is a first for me actually). I'm wondering if I'm doing something that might make other girls hesitant to approach me/respond to my approaches. I realise that I might have some self bias over how I'm contributing to the issue so if there are any questions that could provide more info (within reason) I'd be happy to answer.
