Positive ovulation test 3 weeks after D&C

Lee

So I had a D&c 3 weeks ago after a missed miscarriage at 10 weeks.

2 days away my ovulation test was negative, today is was peak (solid smiley) it's almost like it skipped the 'high' fertility and went straight to peak.

Would it be accurate.

My HCG was negative 5 days ago
