Hey everyone. I had been on Loestrin 24 for an entire year before I realized that It was in fact the pill that was giving me terrible migraines, so emotional over the littlest things, and I was getting immediate headaches after any type of alcoholic beverage which had never happened to me before. My periods with Loestrin would last about 3 days. I recently asked my doctor if I could change my pill bc it was altering my normal life. She switched me to the generic of Yaz called Ocella. I took my last pill of Loestrin on Wed 9/17, my period usually comes a couple days following but this time it never came, not even any spotting. I started my new pill that Sunday 9/20/08 so it was awful timing bc now Im worrying about being pregnant but also my body taking to a new pill. I always take my pills on time and haven't missed any. I took a pregnancy test on Sunday 9/20 and it was negative and I took another this morning 9/25 which was also negative. Im worried bc I have never missed a period while being on Loestrin and trying to figure out if after being on Loestrin for so long if my periods were just going to stop coming and if this is all a big coincidence.
