I know this may sound like too much information but. I gave birth three months ago and have been taking birth control for the last two months. Ever since birth control, the week before my period I will spot a brownish color. Then the next week I will have a full blown period. The doctor said that was fine and it was just my body getting used to birth control. Well this month (the second month of birth control) the same thing...week before my period I am spotting brown but this time there is a tiny pulsating feeling in my lower left abdomen where cramps usually are. It doesn't hurt. It is just kind of annoying. Was just wondering if anyone has experienced this. * Also this is my third child and I don't recall feeling this after the other two.
