I'm almost 20 years old and started taking BC to regulate my periods a few years ago and help with extreme cramps. I started on Yasmin and was on it for about 5 months and then started seeing a new OBGYN who suggested trying Yaz. I was on Yaz for about a year and a half and it worked great. But then I started getting really painful ovarian cysts. To help with the cysts my doctor switched me to another BC which made me extremely depressed and emotional. Now I am finally on Femcon FE and have been fo about six months. I haven't had a problem with another cyst again and things were working out fine... until about 3 months ago I skipped a period. No big deal I thought to myself, it is definitely not possible for me to be pregnant, its been over a year since I've had sex, so i figured it must just be stress or the way I'm eating or something.. Well it's been 3 months and still no period. I know most ladies would love to not have one but I'm starting to worry if this is something that is normal. I honestly don't know if it has anything to do with Femcon but I have a strong feeling it does because I haven't been stressed, my eating habits haven't changed and I know it is not possible for me to be pregnant. I am going to see my OBGYN soon if I still don't have one after this next pack but I am just wondering if anyone else has experienced the lack of a period as a side effect of this medicine because on this site I mostly only see women who have it too often.
