"i have been on this pill for over a year now. i was first on ortho tri cyclen lo (tr sprintec is the generic for this) and i absolutely loved it. i never felt moody crampy or had heavy periods. i switched to tri sprintec due to insurance, not for any side effect reasons, i was disappointed to change but i was happy it was basically the same. i feel slightly moody during the first week just like you would during pms (3-4 first pills in the pack) but no physical changes. my period usually arrives 2-3 days after my pack ends and lasts about 5-6 days and is pretty light except for about a day or two of normal bleeding. i know medications affect everyone differently, so i suggest trying it before letting any negative review sway you."
