My cycles are getting shorter??

[Nixnax]

I’m putting this to the floor in the hope that someone is experiencing the same and can help me out.

My cycles appear to be on the decline in length. My last 5 have been

26 days
25 days
30 days (discounting this one as holiday flying disrupted my ovulation and made it late)
24 days
23 days

I was stable at 26 days for around 6/7 months, then it started to reduce by one day per cycle.

I’m approaching 35 and getting worried that my fertility is declining.

I’ve had my CD21 bloods done and I’m having my CD3/4 bloods on Monday. I’ll get the results in a week.

Is anyone else having this issue and have you had any other tests done?

I want to go to my GP prepared in a weeks time. My GP is quite dismissive, and has already said that they won’t refer me until we’ve been trying for 2 years! I’m 35 and Nov, and we’ve been trying for 14 months, surely that should be taken into consideration?!

Any advice is much appreciated
