Is it possible to get IB at 11dpo after a faint positive?

Rebecca • 27, TTC my second baby. I love my husband for giving me baby #1 who is the most amazing gift in the world!!
Ok so at 8-9dpo I got the below faint lines, today 10-11dpo I had spotted when I wiped, I've checked my cervix which is super soft and squishy and no more blood so far, i didn't think it was possible to get faint positives before implantation? Has this happened to anyone else? I'm due AF in two days time.
