Ive been taking birth control for over 2.5 years. I just started Lo Loestrin in the last month and a half in order to relieve cramping pain. First month went fine, brown discharge on the last iron pill.. Im in the second week of the 2nd pack and I've had a light brown discharge the last couple of days. I recently had intercourse a few hours ago and now its a light pink when I wipe. What is going on? I take my pills around 8:30a-9a every morning. I know the time just changed so that could be a difference but other than that.

Ive also had crazy mood swings starting the second pack so Im currently trying to move to a new BC pill.
