So since i had max i have had very irregular periods 5-6 weeks on for iver a week then few days later on again this month i had quite a large clot went to doctor he said it maybe that my womb infection didn't clear up properly or the pill i am on is not agreeing with me but ive had the same one for years and never had a problem with it so why now and also said it could be that i have some placenta left in and i need to go for a scan i go on holiday next week so will do that as soon as i get home anyone else had this problem?
