This is an ovulation test but, could it be a sign?

My husband and I have been trying for 6.5 years now. 4 miscarriages.

My period was due yesterday/today. No sign of her coming over that low random cramping the past two days.

Again, this is an ovulation test.

I usually stop taking OPKs after my peak day (day 13 or 14)so, I’m not sure how they continue to look after but, that second line seems to be REALLY dark for period time.

Could this be a sign of pregnancy?

DEFINITELY getting a pregnancy test for tomorrow morning.
