My period ended on 25th August (have been irregular after stopping depo 9 months ago) and now I've been spotting then medium level bleeding from day 13 to 17 of cycle? My periods used to be every 4 weeks before the shot, now they are every 6, wondering if now this new one has started I'm going to get another in 4 weeks and it will become regular. I've also been taking angus castus for 10 days. Seen cases of it working as quickly as 1 week before so fingers crossed
