All pills will act differently with your periods. I was on Ortho-Cept. and I had 9 days heavy periods, then I went on Alesse I had 5-7 days normal periods, tried the patch had 3 days of HEAVY bleeding and a couple with spotting. And now Im on Microgestin and I get my Period on Monday night and its gone by wednesday-- just get a lil when i wipe for a day or so after that.. but its great!! No complaints - Just see if your next period changes. You just started your pills anything can happen within the next 3 mths. More then likely you will have light periods! Enjoy them and dont' get all freaked out! Its a good thing!
