"i&#039;m 17 years old and got started on birth control because my periods were 9 days long with severe side effects. i first went on the shot called depo-provera, that was the worst experience of my life. i was having my periods every single day. the doctors told me it was normal and it would regulate after my third shot; however, the 4th shot came and same issues with no end in sight. terrible cramps, headache, even vomiting. when my doctor switched me over to loestrin i had instant results. my period is now regulated to a 4 day cycle once a month. i do have cramps as a side effect, but they have gotten much better. before loestrin i would curl up in a ball and cry from the severity of the cramps. i would recommend this birth control to anyone."
