Hi, I am on day 39 of my usually 30-34 day cycle, and I have none of the usual signs of my period arriving any time soon, I usually have very sore breasts, bloating and general moodiness, all normal for me, but now nothing! I have done a home pregnancy test yesterday and it was negative. I am 33 years old, I have been having regular sex, my last recent pap smear was all normal. Should I be worried?
