i ended my period and took my first pill in new pack i was on vacation so i forgot to take 4 pills .. i notcied i started my period again so took 2 pills and stoped it and kept going on with the pack . a week later i lost a pill so i thought it was best to stop the pack and wait till i get my period again it only last 2 days and was extremly light ( which is not normal for me ) then since i have a light brown discharge .. i am worried what does this mean ?
