Can anyone help with opks?

[mmmgoats]

Using internet cheapies and have confused myself.
Thursday I got a dark line.
Friday I got a line slightly darker than the control
Today is slightly lighter than the control.
Does that mean I’ve missed the surge now? Is it still worth dtd today and tomorrow? (have been away!)

Thanks!

Possibly but I would do it anyway ! I'm new to OPK's but if it's still quite a dark like I would just go for it, maybe the line is slightly lighter because urine less concentrated or something ? It's worth a shot !

@mmmgoats if you had an opk that is darker than the control then that was positive, that was the surge.
After that positive opk you will likely ovulate between 12-36 hours after. The line may not be dark again but that is normal. You may still be in time so I would get DTD.
You can chart your temperature to see if you get a rise which will confirm when you have ovulated. Good luck 🤞🏻

Thank you both! I thoroughly confused myself as I wasn't sure about where the window fell in relation to the positive OPK.
