Last month my cycle lasted for about a week, where as it usually be 5-6 days at most. This month it started around the same time as last month. Only way lighter, and by the third day little to almost nothing. I take the Gidless pill every day, same time & nevery miss a pill. I had sex unprotected with my boyfriend on Monday & my period started the Thursday. Should I be concerned? I've had the basic period symptoms and my body does not seem to be behaving any differently. Just having a light period flow.
