Breakthrough bleeding without missing any pills
I have been on birth control for 9 mo. I experience spotting for the first 3-4 months, but have not had any since. My doctor said this was normal and my body was just adjusting to the pills. Yesterday I began to spot for the first time in 5 mo. (My period is a week away) I have not missed any pills and I do not smoke. The only thing I did differently this weekend was to have a few drinks over the fourth (like 3-4... I do not normally drink). Can drinking be the culprit? Also, is it OK to have sex when I am still taking my pills, but spotting? Thanks
