Lost at 8 weeks

Toya

I miscarriage December 10-11, 2015 and my first period came on January 10,2016.

Me and hubby had unprotected sex last night. I know this may sound a lil crazy but how would I know if I'm still fertlie from the miscarriage? I still doc down my cycle & my calendar application is still crazy cause of everything. But I know u usually start ovulation about a week after your period.

But I'm so losed on this one

HELP PLEASE
