Hi best wishes to you.I hope you can help me out.For the past 3 months or so i've been having a 28 day cycle.AF was supposed 2 come on Monday but it didnt.About two hours ago i thought it had arrived but now i'm sure if it is really AF.Between that time and now i've had very little bleeding.Only saw a little brown the 1st time i wiped and the 2nd time it was pinkish/reddish and very little.I'm wearing a napkin in case and there's not a sign of it.Sorry about all the gross details.I'm 16DPO.Is it possible for implantation to take place this late?My first guess is that it's AF being freaky but i'm not sure so that's why i need your input.Normally when AF arrives it's definitely more than what i'm seeing now.I was really hoping 4 a BFP this month but i'm now i'm giving up hope.Thanks for any reply.
