My periods have been a bit irregular for a while but only few days either way so not too worried. However I am now on my third period this month. I bled for 6 days, then week off, then 5 days bleeding, then 3 days off and now bleeding again since yesterday. I am pretty sure it isn't preg/ misc as DH has had a vasectomy. It could be stress. No other ideas. Would you wait to see what happens or go see doctor asap?
