Haven t been on the pill for years, but decided to go back on as my 2nd child is now 8months old. Started taking Yasmin 10 days ago, from the 1st day of my period as instructed. The 1st couple of days were fine as i usually suffer with painful, heavy periods and they seemed a little lighter. I still had pain and had to take pain killers but wasn't as extremely intense as usual. I started to have intense stabbing pains in my stomach over a 2 day period but pain killers stopped that. But even now, im still bleeding and getting menstrual cramps even though my period should have finished 5 days ago. Was going to hold on to Yasmin for at least a month to see how it goes but with the lack of energy, tiredness, nausea, pains im finding it hard to be a mum of two active young children!
