I've been on Loestrin for about 4 or 5 months. I didn't even have a period last month and haven't gotten one this month (I'm not pregnant). I had some breakthrough bleeding the first month and second months, but none anymore. I take Loestrin because of debilitating severe cramps and I haven't had any in months after starting this pill. The only problem I've been having is that I get extremely nauseous when I eat anything. The funny thing is that I get super hungry a little while later and the vicious cycle starts over. I don't know if it is because of this pill. I had extremely low blood pressure before taking it, so it could be because of that.
