Last two periods were light than normal. In between the two periods I had light bleeding for a few days as well. On birth control, Tested negative for pregnancy, health problem?

Light "periods" ?'s. At 22, stress from work, school, heavy exercise or emotional stress can inhibit ovulation and delay "normal" menstrual events. If your "birth control" happens to be depo-progesterone shots, or a progesterone type of birth control like Nexplanon, these events are common. If not, ask your gyn about polycystic ovarian syndrome (PCOS), which can cause the same effect. .
