High fertility again after peak fertility

Hi everyone! I got my IUD taken out 2/22 and started bleeding 2/24-2/26. I started using the clear blue advanced digital opk to see what my cycle looks like since I had none with the IUD. I got my first high fertility flashing smiley face on 2/27 and that continues through 3/2. I then got my peak fertility solid smiley face for 3/3 & 3/4. I was curious and has more strips so i tested yesterday (3/5) and it was low. Tested again this morning and got a high fertility flashing smiley face. Has anyone else had this happen before? This is new territory as I didn't truly track for my first two pregnancies! The first one happened when we "stopped trying" (🙄) and the second pregnancy happened when I was 4/5 months postpartum! I appreciate any advice from you wonderful ladies! Baby dust to y'all!!!
