"i switched from lo loestrin fe to apri because i was getting married and wanted to ensure i was having a monthly period (no pregnancy scares for me, thanks). i didn&#039;t experience many side effects at first, but with my first period on the new pill came painful cramping and heavy bleeding. mind you, i hadn&#039;t had a real period in about a year thanks to lo lo fe, but that sort of pain was why i started birth control in the first place. i&#039;ve been on it about four months now and have seen a significant decrease in my sex drive, which, hello, sucks (newlywed, remember?). i&#039;ve also seen mood swings and nausea the last couple months as my body has been adjusting, and i&#039;m just not about that life. switching as soon as i can."
