So I had a super long period which is totally normal for me at the moment after coming off nexplanon a year ago ish. Well the last 3 days my period was super light or stopped and started again and me and my so BD and according to glow I ovulated just after my period finished/while I was light bleeding. So I could be around 5-6dpo and I've just started bleeding like a dark pink colour. My question is could it be implantation or something else?
