I have been trying to get pregnant me and my boyfriend.. my last period was may 14th and it was regular.. im due for my period now and no sign of it I am now 4 days late I've been cramping for a week and my breast are vert tender my nipple area is also turned a brown color.. I have been getting sick in the morning when I wake and in the night when I go to bed it feels like I'm going to have my period but it don't show.. I took a hpt when I was 3 days late and came back negative.. im also bloating and needing to pee more often.. can I be pregnant?
