I did not have sex during my last ovulation, but I have missed the first day of my period this month. I took a pregnancy test, and it showed up negative. I haven't had any symptoms for my period or pregnancy. What could be the issue?


Sometimes cycles change due to a shift in hormones. It could be because of stress, lack of sleep, change in activity levels, or a variety of reasons.
