"i absolutely loved orthotricyclen! i was always irregular and had very bad mood swings, cramps, headaches, and nausea associated with pms and my period. the first couple of months, i experienced occasional nausea and dizziness but that&#039;s to be expected when starting a new hormonal treatment. my periods shortened to four days instead of six or seven and i was able to pinpoint my periods each month while on the pill. i stopped taking it for a few years but i&#039;m getting ready to get back on it this next week and i&#039;m looking forward to it! after i stopped taking it, however, my periods became irregular again after a few months of discontinuing the pill."
