"i am 23. i was on a pill from when i was 16-22. i switched to a mirena iud for 6 months (gave me horrible yeast infections and i literally had my period for 6 months). i have been taking gildess fe 1.5/30 for a year. nothing to complain about, no attributable weight gain or mood changes. but, in all the years i have been on birth control i would get my period 48 hours after taking the last active pill, like clockwork. however, this month, it&#039;s been 5 days and no period. assuming i&#039;m not pregnant (very low chance, we use condoms as well) then this pill is great, but not having a period is making me stressed!"
