I usually get my period around the 2nd of each month. Today is October 4th and I still have not gotten it yet. I took 2 pregnancy tests and both came back negative. I have also been taking aspirin and black cohosh to make it come sooner but it is still not here? Should I be worried? I have been feeling stressed lately and I'm just getting over a really bad cold so I don't know if those factors would contribute to my period being late but I'm kind of getting nervous. What should I do? Have any of you encountered this problem?
