So I've been doing OPK's for the last week, nothing nothing nothing and then four days ago I got a super faint line, followed by a slightly darker one each day... I have also had tingly slighty crampy things happening over my left ovary site since 2 days ago.

I'm confused because as far as I had been told, they should turn positive when you are going to O, so why am I getting gradually darker ones when the hormone is only present a short time???

Any help would be great as I'm a bit confused...

TIA
