does anyone know whats going on with this

Lindsey

I've charted for a few months now and never have I had a drop during af ..I'm not taking meds or doing anything different but also a couple of days ago I also had a near positive opk and this period from the start as been completely the opposite to what I'm used to it's normally heavy and painful and I've never spotted and this time it's started with pink spotting for a day and it's been dark red and light for the past 3 days sorry for tmi but I'm just wondering what's going on and if anybody else as been in the same boat ..I did an hpt about a week ago and it was bfn ...baby dust to all xx
