I am gonna be 19 next month. Me and my boyfriend have been having sex for over an year now at least 3-4 days a month but multiple times in the same day.

We don't like using condom as it often spoils the experience for me.

Our primary method of birth control is withdrawal(which does not always work) or 72 hour pill (5-6 times now) .

However, every time my periods get late it scares the hell outta me.

I am considering birth control pills but I am not sure if it's healthy for a person of my age. What should I do?
