Help! My cycle is 24 days long

Ch

Hello all,

I'm charlotte aged 27 and ttc for over a year now.

I've noticed my cycles have become shorter and shorter throughout my ttc time. I used to have a 28-32 day period. However the past few months my periods have been 27, 26 and now 24 day cycles!

My breasts are sore each month and I've got spots on my face (never suffered acne until now).

Is my fertility declining? Help! Any advice would be welcome
