Okay, so had my dd in January - periods returned in May and have now had 3 incl. this one. The first two were completely as I remembered them, but this one has been going on for ages - now about 10 days. At the beginning of this period I restarted the pill (combined) - might that have 'extended' it in some way, or do I need to see my GP? Flow is very light now, but just going on, and on, and on....
