To ask if you’d ring the GP over this

[cheerioagain]

One late period, CD41. Usually I am always CD30-31, very regular, have always been. Latest on I’ve ever been was CD34 and that was a fluke - I understand stress, dietary changes can affect it but I’ve not done anything different this month to any other month.

I had all the signs of ovulation as usual around CD14-16… but mysteriously no period. That means a luteal phase of 25+ days. Not yet TTC but did a HCG strip just in case on CD32 but it was negative.

I am in my 20s. Any ideas?

Yes without other symptoms/issues it's usually 3 missed periods and see gp . But yes do another test.
