Pregnant or not?

Lately I've been having quite a few headaches and through out the day I feel pretty nauseous sometimes, today my nipples were super sensitive, I had slight cramping (like little bubbles on my right side and in the middle), my CP is very soft and feels as though it's closed and im also late with my period. My boyfriend lives overseas and I'm definitely worried that I could be pregnant, I'll take a pregnancy test as soon as I can but any thoughts for now.
