Hi sorry for the TMI pictures but I am so confused and need advice/help. It's day 18 of my 33 day cycle (5 days past ovulation, me and my partner had intercourse 4 days ago). The picture with the very light pink spotting happened right after I had egg white cervical mucus with white mixed in followed by cramps (around 12:00PM noon), the picture with dark red what happened just now (around 7:20PM). I usually don't track my period or My cycles because they're very irregular, at first I thought it was implantation, then I thought it was ovulation but now it's so dark red that I'm confused.

Opinions??
