Very faint positive FRER but negative OVRY

Hi gals. I've had 2 losses this year, so all this TTC stuff makes me super anxious. I've been testing since 5 days before my period was due with OVRY tests. They've all been negative. My period is now 2 days overdue. I bought a FRER test and took it this morning along with another OVRY test. FRER shows very faintly positive but OVRY is still negative. Has anyone else experienced this with OVRY tests? I heard good things and read lots of reviews so I'm unsure of what to think.
