Should I be worried?

Sam

Me and my boyfriend do not want a kid right now, weve used condoms religiously. We had a couple condoms break in october/november, but since my last period, our condoms have been holding strong. I'm not on birth control. My periods are sometimes late by a day or two or 5, but now its 8 days late, should I be worried? I'm not stressed or anything so it should come...

I've had to pee a ton and I've been nauseous on and off (however, I am getting off the stomach flu)
