I take Generess FE and have missed a period once on it before. Only this time, I have a boyfriend and we are sexually active. We use more than one form of protection though when we are having intercourse (my birth control, a condom, and the pull out method). I did not get my period as expected this month and took a Clear Blue pregnancy test just to be sure, 3 days after my period was supposed to start and it came back Not Pregnant , which is great! I have had a lot of stress this month between a death of a friend, a major argument with my boyfriend that lasted a few days, and an issue stemming from my summer job (I m in college). Does stress like this cause a missed period even though I m on birth control which is supposed to regulate it? The hypochondriac in me is worried that I m going through some time of premature menopause. SOS!
