I’ve got positives on early detection tests 6 and 5 days before af due.

Today 3 days later I’m now 3 days before af and took normal level strip test and COMPLETE NEGATIVE???

I’m so scared I don’t understand.

I had a miscarriage 8 weeks 1 day ago and thinking the first ones could have been from that? I don’t know has anyone had this experience normally I get positives on normal strip tests days before.
