Yesterday at 9 dpo, according to glow, I had some pink spotting when I wiped. I had some more pink looking discharge when I wiped or felt inside today but not enough to even get on a liner. Could this be IB or is it more likely my period starting 5 days early? I am TTC #1 so I am not familiar with my body conceiving. Also if it is IB when do you think a test would come back positive?
