Hi,
Just wondered if anyone has used the FR ov tests? I'm not sure i'm reading mine right!! I have been testing for 5 days firstly i had a really really squint to look faint line then i have had for the last 3 days a very clear line but not as dark or strong as the control line and today i am back to the very faint squint to look line. Does this mean i ov'ed? It would be the right time for me to ov but as the test line wasn't the same as the control line wondered if this was a positive result!!
Any insight would be good!
Thank you.
