How many DPO?

Sa

How many DPO do you guys think I was when I found out? I took a clearblue digital on the day I got my faint positive (24th)!

and it said “not pregnant”..I know it needs like 50mui of hcg to detect it, but I’m not sure about how many DPO I could be..my period was due Wednesday the 25th and I got my positive the 24th..(the top test)
