Positive multiple WONDFO tests but FRER negative

[Doremifasol]

Ok, please bear with me... 5 years of secondary infertility, 6 miscarriages... my head is all over the place atm as I just seen multiple positive WODFO tests but frer is negative!!!
I only ovulated 5 days ago and it was quite early for me ( day 10, usually day 15). I have always v noticable ovulation signs, horrible sharp pain, bloating, nausea and egg white discharge. I know my body, all of that happened around day 10. Fast forward to yesterday- I wiped and seen bit of fresh blood. Was thinking to myself- why bleeding now, if I already ovulated. I sometimes have ovulation bleeding but it's at the same day when I getvthe worst stabbing ovary pain. So I did another OPK which was positive. Was very confused. This morning more blood when wiping and even more positive OPK ( as in test line v v v dark). As I have hundreds of tests at home I decided to do HCG one ( 5 actually🙈).
lines have appeared straight away. BUT FRER is negative🙁
what on earth is going on...?

Hi there.

Apologies I skimmed over your post so apologies if this is irrelevant!

I had the window tests from Amazon and got all negatives and then two positives out of the blue. My frer's didn't turn positive until after my period was due.

I had used two tests with the same urine so was pretty sure it wasn't a dodgy test.

Apologies auto correct!

Your tests look a lot darker than min did also.

If you're 5 days post ovulation that's really early to have a positive, implantation usually occurs 6-12dpo then your hcg has to rise enough to be picked up by the test. I'd leave it a couple more days to test, 10 was the earliest I tested but 12-14 would give you a darker test
