I am a sexually active 19 year old woman and my boyfriend ejaculates inside me. I am on birth control (the pill form). I started my period on time which was Monday night but it was dark brown and it only lasted until Tuesday night. Does this mean I could be pregnant?

This is completely normal darling. It's just browner as it's "old blood". The pill prevents the period from happening, so the blood stays in there until the week you're off. Assuming it doesn't have a strong odour, and you're not in pain or have noticeable changes to the surface of your vagina, there's nothing to worry about.

With regards to pregnancy, it's quite unlikely.
