"i have only been on this pill for 3 weeks now, but wanted to insert my experience because it seems pretty different than some of the other reviewers. i had light spotting for about a week and a half four days into taking the pill, then it completely stopped. i didn&#039;t experience any other side effects until the next week: dizziness, lightheadedness, and something i can only describe as a &quot;mental cloudiness.&quot; these effects would normally last 15 hours after taking the pill (i take it at 9pm). nothing i do could help it--eating, drinking water, you name it. feels kind of like i have morning sickness or something until 2pm, but i would like to add that that is not consistently every day. i take my pill at the same time every day."
