Should I:

I'm three days late for my period, I'm usually pretty punctual, I stopped taking my birth control about two months ago cause it was making my period a little wack, I had sex with a condom during my fertile period about two weeks ago, before starting again then hadn't had sex in about 4 months due to long distance before that. I'm 19 and my boyfriend goes to college all the way across the country in two weeks...
