Can Light Periods Be Sign Of Pregnancy While I Usually Have Longer Periods ?

My cycle usually lasts 32 days. My last period was on 23.5. and it ended on 28.5. Last two months my cycles were 42 and 38 days long. I had protected sex on 6.6. (we used a condom as protection). My period is now about 12 days late. My breasts are sensitive to touch and I ve been having cramps similar to when I m about to get my period. On 1.7. and 2.7. I had a light bleed, similar to last days of my period and since then nothing. I don t feel nausea or morning sickness. Is it possible that I might be pregnant?
