I've been on the pill for over a year now, my last one didn't work well for me (anxiety and? depression) so i switched to lo loestrin fe and i took it the first day of my period (may 17) and i haven't gotten my period yet and im starting my second pack today. i didn't spot, i didnt have any kind of bleeding throughout the month i was on it. could i be pregnant? should i be worried or is this normal?
