Confused&frustrated - in late period/bfn limbo, but had suspected implantation bleed a week before due period?

Take another test in a week if your period doesn't arrive. Sometimes stress can cause your period to be late. If the HPT is negative in another week have a blood test done. I would be seeking another G.P. if he/she wants you to wait an entire month in discomfort. Best of Luck to You!
