My period ended on the 2 of January and then 3 days after my period ended i spot pink very light just one spot two days in a row. Then a week later nauseous kicks in and and the cramping started a day after the spotting and still continues for the last 3 weeks now and my breast have been sore for a week and there getting bugger as well i went from a 38B to a 30C and I've also lost 20lbs in the last 3 weeks and my diet hasn't changed. Could i be pregnant?

I hope i am me and my biyfriend been trying for a whole month now. My body has faked a pregnancy clear up till my period started then all my symptoms wen't away real quick.
