I am on my 3rd pack, 2nd week. My doctor prescribed this when I complained of heavy and painful periods, and also bleeding in between periods. The first month I started taking this, I had "breakthrough bleeding" that was more like a light period, for 2 weeks BEFORE my actual period. Yes, I was bleeding for 3 weeks out of the month. The second month, there was "breakthrough bleeding" again, this time 1 week before my actual period. So I was bleeding for a total of 2 weeks of the month. Now I'm on my third month (because they say to give your body 3 months to adjust). After my period this time, I had light spotting for 2 full weeks, whereas I didn't the prior 2 months. Then today I started bleeding again, only it was more than just bleeding: it feels like a real period with cramps. I wasn't prepared and basically had an accident. I only JUST had my real period 2 weeks ago. I seem to be bleeding more often now than before I started on Loestrin, so now I'm wondering why I'm doing this to myself. Should I just suck it up and take Midol during my periods and forget about these bc pills altogether?
