preggers?

So I don't get my period till 6 days from now. But I've been very very tired and I've been puking since last Friday. Tomorrow will be a full week of puking. Not even one day of rest from it. I never got sick with my daughter tho. Me and my guy did have unprotected sex while I was ovulating. I did take a test . It was neg. just wondering if anyone has anything they can tell me. Oh and my last cycle was 7 days late. Don't know if that helps or if it's unrelated. But I've always been on time since using glow.
