Confused by OPKs

[Whoevenknowswhatisgoingon]

I have just started using OPKs this month & I am confused. I did a test this morning which looked like it was almost positive but it is now lighter when I have tested again.

Has this ever happened to anyone else before? Am I likely to have reached peak during the night and missed it or is it still to come?

Sorry I am not sure how to post photos!

It's possible you have a short lh surge. I've definitely missed my positive in the past. I would carry on dtd over the next few days.

Are you recently off hormonal birth control? It could be your cycle settling down. How long is your cycle?

Thanks @venusstarr. I have been off birth control for several years. We managed to DTD this morning so will definitely keep going & will also keep testing to check incase I haven't peaked yet

My cycle seems to fluctuate between 28 & 35 days. I have on CD17 today
