When should I take a pregnancy test? And do you think I am pregnant?

Okay, Well, I am 14 years old. My Boyfriend and
I have been dating for almost eight months, And we have been sexually active for a while now.
I don’t need criticism right now, I just need advice, please and thank you. I started taking birth control pills, and on the packet it says to continue using back up birth control, (Condoms, Spermicide, ect..) for at least 7 days. And ON my 7th day of being on the pill and taking it correctly, my boyfriend and I had unprotected sex, and he did not pull out. (Not smart, I know.)
I’ve been having A LOT of early pregnancy symptoms. Spotting, a lot. Tender breasts, my nipples have darkened a bit. I’ve been crampy. it’s been about 2 weeks. My period is due may 14th. Today my spotting got a lot heavier, and I don’t know if it’s a regular period or not. But my boyfriend and I also had a lottt of sex yesterday, and I’ve read some things about when you’re pregnant and you have sex you can bleed. I have never had an early period. I don’t know if my birth control is doing it, if the sex did it, orr.. I just don’t know!!!! I’m so scared. and I don’t know when to affectively take a pregnancy test either. Should I wait for the 14th? or should I take it now? PLEASE HELP MEEE!!!
