could I be pregnant?

Silkina

I'm cycle day 25 this is the 4th day on a row after I eat I get nauseous and throw up.. my breasts are sore. I have take so many naps this last week.. I'm tired and moody. I still got a week before my cycle so it's to early to test. is it possible I could be pregnant? If i am I don't know how to tell the father since we haven't spoken for about a week now.. any bit of advice?
