How frustrating! Spotting and cramps are not a lot of fun. Having to use a minipad or change tampons twice a day, may be spotting. Spotting that continues past 2 to 3 packs of pills should be investigated. However, heavy bleeding with needing to change every few hours and cramping should be investigated sooner. So, if you are spotting and continuing to have problems with a second or third pack, it is time to contact your health care provider for evaluation. This new brand of birth control may not be the right choice for you.
