False positive ovulation test?

Hayle • 5 yr old daughter. 1 👼🏼 1-23-19. Ttc baby #2.

ovulation test in the comments, but could this be positive from left over hcg? I had a d&c 2 weeks ago. Haven’t done blood work. If not then crappy timing since I have my saline ultrasound tomorrow and probably can’t bd before it 🙄
