Hi, My university pharmacist recently started carrying a generic form of my birth control pills. This month has been my first full month on the new pill; my period came 2 days later than it did on my old pills and ended today, 4 days earlier than usual. Two weeks ago I started a new work out regiment and changed my diet slightly, but I am wondering if these changes to my menstrual cycle are normal and if I should be worried about any sexual activity (I still have 2 days of iron pills left before my next pack).View Thread
