Maybe. Are you temping and charting to confirm ovulation? If so and if you ovulation date was last Thursday, you may be able to turn a test in a couple of days. The earliest I got a BFP was +10. Good luck!
With my LO, I had implantation spotting on day 3 and 8 after ovulating, then tested positive on day 11 after ovulation. I had just figured it was my period about to come, but nope! My spotting was very slight, light pink in color, and not enough to notice except when wiping.
Re: Possibly pregnant?
Wishing you luck!
