I was wondering if I could be pregnant. I had my last period on Oct. 20, 2012 I should have received my period again 11/12 but it never came until 5 days later. Then when it did it was nothing more than a very light period then end up to just spotting. I am still spotting but most I only see it when I wipe. I’ve been having headaches, swollen breast, large nipple and a little darker than normal. Eating a lot and very tired easily. Took 1 test today in the afternoon and it was negative. What does you think I should do?
