I came off my period about 14 days ago. 5 Of those days during my period I took the pill then quit...i usually have my period for 7 days but it lasted a couple days longer and it was brown in color. now my fiance and i hav been having sex regularly since ive came off and for the las few days i hav been having tenderness in my breast and the lower area of my stomach has been really tender. also ive been extremely gassy, constipated, headaches, and sweet smelling discharge more watery than usual. could i be pregnant? im not due for my period until the 12th of december(i think)....
