I really don't know where to even begin!!! My last menstrual cycle Was November 28th. I was expected to have one around Christmas Eve and nothing came!!! since then I've been having really sore, achy breasts... underneath and near my armpit area. I've been craving lots of sugars. I am extremely tired!! I have taken 2 pregnancy tests.. 1 on December 27th and another on December 31st. both turned out to be negative. do you think I took the test too early??
