NuvaRing and hair loss

I generally like my Nuvaring, when I'm responsible about using it correctly. I feel confident that it works and I can forget about it most of the time, until I forget to take it out or put it in on the right day. I have used it to skip a period every once in a while. When used inconsistently like that, in combo with not taking out or putting in on the right days, I developed terrible migraines and strange neurological symptoms, like lightheadedness and scalp numbness/tingling. But when I used it regularly again, the symptoms disappeared. I do think I gained weight on it.
