Can i be pregnant? My periods used to be irregular but the past 2years they have been right on target. My husband and i have sex every other day or every day sometimes. My period last month came a week early was spotty brown and red then one day heavy then spotting lasted 3 to 4 days. Now this month i am a week late so far. tired 24/7, cramping, sensitive to smell, some nausea but haven't thrown up, cravings,a lot of pressure in lower belly, bloating,gassy, hungry a lot. i took a pregnancy test today and it was negative. what should i do? could i be pregnant? im not under stress or anything and we have been wanting a baby.
