I am just finishing my first month of Trinessa. I have four green pills left. I started the pills the Sunday of my period but I also got my period during the third week of active pills and it ended this past Sunday (when I started my inactives). I just had sex and my guy may have came inside. I know the pill isn't 100%, but should I worry about pregnancy since I'm new to the pill and do not have my period during my inactives? I'm really new to all this and want to make sure I'm getting it right and protecting myself as much as possible. I have been taking my pills everyday around the same time at night
