<s>[INST] I'm 47, and still take Mercillon pill; mainly to control when I have a period and keep light. My GP said okay to take until I'm 50. I'm in good health. Over the last 3/4 months a couple of days into the 7-day pill free break I've been woken up early in the morning with low abdominal period like pains.  Bleed starts as always approx 4-days after ending pill.  Once period over and I'm back on the pill I'm absolutely fine.  Do I need to be worrying about ovarian or other problems, or could this just be something to do with hormones? [/INST] Hi,Thanks for writing to HCM.That is absolutely normal, and nothing to worry about it. RegardsDr. Ashish Verma </s>
