Progesterone suppository help

Looking for some advice! My RE started me on progesterone suppositories this month from ovulation until the day of my estimated period if test is negative or 10 weeks if positive. I'm due for AF today or tomorrow & testing negative (maybe my crazy self is seeing a faint line but probably not). I'm testing again tomorrow but I'm just so nervous to stop in case maybe I implanted late? Ive read of people getting BFP 14 or more DPO so I don't want to screw up and stop and then cause myself another loss. Has anyone been in this situation before?
