I recently started taking TriNessa Lo (on my 2nd pack) and my period just started a day early. I still have one more blue pill left to take before I start taking the green placebo pills tomorrow. I take it in the evening (8:00 pm) because that's the most convenient time for me. Should I be concerned that my period is starting before I'm on the placebo pills? Last month, my period didn't start until the very end of my placebo week so I'm just very confused right now.
