Hi, this is my 7th cycle ttc and I am currently 3 days late for my period according to my premom app. My lh readings have been up and down through the month and are spiking again tonight. I am unsure which one would of been my true peak so any advice would be greatly appreciated. Also, has anyone has this much of a fluctuation in lh during a cycle as my other 6 cycles have been completely regular I have never missed a period yet I'm 3 days late with a bunch of confusing tests for the month.
