Hi! I just had sex for the first time on December 2nd and my period due date was December 16th. Unfortunately, it didnt come on. It's been 3 days now, so should I be worried or is this a phase that all virgins go through after having sex for the first time.
If you had protected sex then you have virtually nothing to worry about. My period has never been normal, but I'm sure you are not pregnant. I would give it two weeks. If you have not started your period by then, you might want to talk to your parent or a doctor--depending on how old you are.
