There is no such thing as a faint opk..you usually always have a faint line.so it's just picking up your regular hormones

Opk always have a line on them.

Thats not a faint ovulation test theirs always a line upon them and this is clearly negative. If its positive the line must be equal or darker to the control band line. I had a positive ovulation test before hcg and it was very dark thats how i knew i was pregnant as it was a week before AF was due.

You get a lh surge before period so this is why the faint ovulation test
