I didn't get my period this mo im not preg but did need planb today now i'm spotting i'm having a panic attack will i ever get my period? y didn't i?

Many reasons...: Hormones, stress, weight changes and many other factors can affect when you get your period (as well as, the obvious pregnancy). See your gyn to determine if any evaluation needs to be done - while you are there you can talk about effective/reliable forms of birth control. As a reminder, you want to also use a condom to prevent STDs

Get checked: When you say you are not pregnant, are you saying you haven't been sexually active? That's the only way you can say for sure. Please see a trusted medical provider or gynecologist as soon as possible. Sound information and guidance from an experienced professional will move you from panic to a plan of action that makes sense for you. Hope that helps!
