Discharge?

Evening ladies,

Does anyone know what this sort of discharge is? I am not due my AF until 14/12 but when I was ovulating last week I used my clearblue fertility monitor and tested peak on two days which we had BD both days and on the high days.

We have been trying since September after being on the pill for quite few years.

I have experienced lower stomach cramps and bad back pain Monday-Wednesday this week.

Can anyone advice what they think it means? I have felt my cervix and it feels soft! Opinions would be great, really hoping for some baby dust this month would be amazing! Thank you in advance.
