At the beginning of March I started working out and my cycle started late (end of march) and it only lasted about 2 days and it was very light. I do not think I ovulated in March. My cycle used to be like clockwork. I cut back on the exercise to see if my cycle would regulate again. April my cycle came on time (end of April) but it was light and about 3 days (light spotting on the 4th day). I do not think I ovulated in April either. (I had no vaginal discharge). I guess my question is, does it mean that if there isn t vaginal discharge I am not ovulating? Could I have thrown off my cycle by exercising too much. I didn t lose any weight during my month of exercise. I went from no exercise to doing about 1 mile in 10 minutes on the elliptical almost every day. My husband and I are trying to conceive to I am concerned about my cycle...
