i'm approximately 20 dpo. we dtd 3x during the fertile window, as best as i could estimate it without an opk. AF is a week late today, and for the last 10 days or so, i've been having food aversions, a little dizziness, and a very hopeful feeling that i might be pg. this morning, i had a little bit of pink/dark pink spotting on the toilet tissue. not brown, not dark red. not feeling crampy, but i think i may have psyched myself up so much about possibly being pregnant that i can't really tell if this is just my period or not.
is 20+dpo too late for it to be implantation bleeding?
