Also, if you got to askapatient.com they will have user reviews of lots of medicines. If you look it up by brand name (Loestrin), you will find many complaints like mine.
All I can say is run like hell from this pill! I took it for 6 years and never had a problem. I switched to Seasonale for 2 years, but that didn't work, so I switched back to Microgestin. I was on it for 2 weeks. In the first week I had intense headaches. Then one week after I started I had the worst headache of my life in addition to numbness in my whole left side, and face, and nausea. I thought I was having a stroke at 21 years old! I endured multiple tests and the doctors found nothing wrong. My anxiety is through the roof! I gave speeches to crowds of 300+ people before without feeling the slightest bit nervous! Today I was scared to stand in the bank because I thought it would be robbed or held up, and I convinced myself I had tetanus! I'm on anti-anxiety meds now and they barely help. The only diagnosis I got is Chronic Severe Anxiety. I've been off it for 1 month and still have severe anxiety and random numbness and chest pains. Please do not take this pill!
