Hi! I'm A 25 Year Old Female And I Really

Hi! I'm a 25 year old female and i really want to get pregnant. About 5 days ago i quit taking my birth control pills and i've been taking them for years now. The same day me and my boyfriend had unprotected sex and 2 days later we did the same again. My period is normally very irregular and i've stop taking my pills before, those times i got my period the same day or the day after i stopped taking them. The last 2 days i've been feeling really sick and my breasts have been very sore. I've never had these symptoms before and i'm wondering if it's possible that i'm pregnant? ( sorry for the bad english but i'm swedish)
