"i was on desogen for 7 years and never got pregnant, had shorter, lighter periods. all medicines have side effects that being said; the down side was slight increase of my blood pressure &amp; slight weight gain. when i was ready to start my family it only took me 2 months to get pregnant. now i have to be on a different pill because i&#039;ve had my baby &amp; our hormones change but haven&#039;t found a pill that works as well as desogen did."
