I lost my virginity and Ive noticed that there's a lot of blood coming out. Im not sure if its my period or something else.. should I go see a doctor already?

It is normal to bleed when you have sex for the first time.

I am sure you are using birth control, and if not that you are ready for children.

Losing your virginity is nothing to take lightly. Yes, sex is fun, but it comes with VERY serious consequences.
