I have been on Cerelle for years due to other pills causing me to have major migraines. Ever since being on it I have had no periods and no bleeding. I fell pregnant and had my DS March 2016, as soon as I was allowed to I went back on Cerelle, again no bleeding, and the last few months or so I have had random bleeding, for example, I've just had a week long bleed, then it had stopped, just gone to the loo wiped and have spotting... should I be worried? I have booked a gp appointment but the soonest I can get an appointment is 2nd March and I wondered if anyone had experienced this at all? Dr Google isn't looking good but I'm a nightmare for googling!
