I don't remember what happened last time. I had one mini period a few weeks ago I think, then two weeks ago started bleeding again, very lightly and only for a couple of days, then after a break of 2 or 3 days started again. Since then it keeps getting lighter and I think it's tailing off, then getting heavier again. When it's lighter it's sort of like lochia, like pink tinged discharge rather than proper period blood. What's going on?
