Hello, I am a married mom of two. My monthly menses is a few days late, however I have not had intercourse (or outercourse) with my husband since my last period. My last period was a few days early, but a 3-4 days of moderate flow. I have mild anemia and have traveled by plane recently. My husband and I use condoms correctly and every time we have intercourse. I am concerned about unplanned pregnancy or perhaps perimenopause.
