Bleeding help?

Michelle

So my period was early this month anyway which was strange for me. Finished my period this month on the 7th but for the last 2 days I’ve been having very dark brown bleeding but only when I wipe.

I’ve been doing digital opks this month with today and yesterday getting flashing smileys so high fertility.

I’m just a little confused as to what’s going on.

I’m booked in to my drs for day 21 bloods on the 23rd based off my period but if I’m bleeding now do I need to change these bloods as I’m unsure if it will be correct or not.

Can anyone help at all?
