I took loestrin for 3 weeks and of all the pills i have ever been on this one is the worst. I have had acne, weight gain, headaches, cramps, no sex drive, anxiety, rapid heart rate, my breast were extremely sore, and depression. I didn't even finish the pack because I was severely paranoid that I was going to have a heart attack. Once I stopped I got my period within 2 days and all of those side effects went away. My only issue now is I haven't had my period since that time. It has only been a month and a pregnancy test came out negative adding to the fact that I don't feel like I did when I was pregnant. It is still frightening though.
