Ovulation positive for 48+hours

So I've never had this happen before. We had a MC oct 31st at 8 weeks. I got my period 6 weeks later(dec 12)
I got a positive O Monday morning and still had a positive late Tuesday night. The pic shows O, sex and strips
Any suggestions why? Or if I have a shot at getting pregnant?
