"i took ortho tri cyclen lo for a year and gained 15 lbs on my 5&#039;1 normally 105 frame. i am 19 and run 50-70 miles a week for track and cross country. i knew there was something wrong, as before i would lose up to 10 lbs during the season. i told my doctor i thought the weight gain was due to the pills, but she insisted it wasn&#039;t. as soon as i got off of otcl, (became single and didn&#039;t need it) i lost those 15 lbs in 3 weeks and shocked my doctor. the pill definitely can, and was, the reason for weight gain. at least i never became pregnant. i have switched to apri since and i hope i don&#039;t go through the same again, anyone have any stories about their experiences with apri?"
