Hi, I have been taking Yasmin since 2004, I had bad menstral cramps and irregular periods which it has sorted. When I first started taking it I use to get headakes and my ears would block, felt like I was on an aeroplane all the time. Those symptioms have gone now.... But recently I have been getting periods (really heavy ones) half way into a pack. This has totally freaked me out. My PMS is horrible, I get depressed and sad 2. I wake up in the middle of the nite with cramps, this happens about a week and a half into a packed also. Think it is doing strange things to me, I am afraid to go off this pill as I dont like the bad pains I use to get before. Speaking to my doctor about this just goes in one ear and out the other really. Has anyone else felt the same?
