Strong bfp 12pt? (500 mcg ovidrel)

Kc
I know i shouldn't have tested yet but I started at 10dpt with cheapies.. The last 3 days they all looked the same so I broke down and did a FReR this morning.. Which was very dark. Anyone still have a strong trigger left at 12dpt? They say 14dpt it should be gone (500mcg dose). TIA
