i have been on birth control for the last 2 mo. i had forgotten to take it for 2 days in a row and so when i took it i ended up taking 3 to catch up. i had a normal period that lasted 7 days and ended last weekend. yesterday i started spotting mid day and it stopped soon after now today when i woke up i am bleeding as if i am having a light period. could it be because of taking the 3 pills?
