I have the same problem as you. Except my missed period hasnt been 5 weeks, I usually get mine on the 6th-9th days and im always regular. Well i still havent gotten mine, ive been feeling sick, my boobs hurts, and so on. But ive taken 3 tests and they have all come back negative. Have you found out what to do, cuz id like to know too.
