Could i be pregnant?

My ovulation was 12-17 this march and i had sex 12-14 everyday. About a week after we had intercourse i started to have off and going pains in my boobs and i never ever got boob pains before my period so thats why i knew something was wrong, im also 3 days from my expected period, having no pms symtoms at all. Im also bloating. Is this a sign?
