If you know that you ovulate/are fertile within the first few days after your period ends - which would be maybe day 7, 8 perhaps? - so you have a 3ww wait until your next period, could you test after 2w or is it best to wait until your period is due? Does the '2ww' just mean the standard 2w between the average time most women are fertile and their period, so if your cycle is different you could test at a different time?
