TTC, what do you think?

I got to see my fiance the weekend of memorial day- 21-25, I didnt get to see him in almost 6 months, he's in the military. Of course we did the deed while I was there, and the last day before I left, It was 4 days before my ovulation period was supposed to start. A week after I got home my breasts got super sore and Ive been ridiculously moody these past three weeks. My breasts only hurt and my mood only changes a week or less before my period starts, and it doesnt start until 6-17. Ive also been having little cramps here and there the past 2 weeks.. Is it possible i could be pregnant? I havent taken a test, i dont want to get my hopes up and get let down , i want to wait until my periods late but it's killing me waiting! What do ya'll think?
