Help?!

Shay🤰💜✌

Never had this before. I got nexplanon out on Nov 29 though I ovulated two days late then had a withdrawal bleed for 6 days and haven't bled for a week now. I had this when I wiped a few minutes ago? Any ideas? If I did ovulate right before that bleed I would be around 12 dpo but if I didn't ovulate then I would just be starting my fertility days if I count the withdrawal bleed as a period. I'm so confused
