pregnant maybe???

So guys I need help!! I'm 16. I'm on birthcontrol. And my boyfriend is 18. Yes we've had sex, unprotected and yes he came inside me. Since I've been on bc (January 5) last Saturday(feb 11) we had sex and I forgot to take my bc till 8 the next morning. (I take it at 9 every night) I took it as soon as I remembered and then took that days at the regular time... I've had tender breast since BEFORE I forgot to take the pill. No ive been really hungry. Bloated and moody for a while now also.... no just yesterday I started having this really weird discharge it's almost like I'm on my period but I'm on the pill and that's not for another 10 days.. it's not really blood but it's kinda brown and it kinda smells... could that be a sign that I'm pregnant?? Please help!!!!!
