Is this a normal pre-period symptom?

Hi everyone, sorry for the tmi picture I’ve tried to crop it as much as possible 😬 But basically my cycles are completely irregular so I’m always left wondering if my pms symptoms are normal! I’m currently on cycle day 31 and feel I did ovulate about 10-15 days ago so think my period is expected, I’ve had a few of my other normal symptoms on and off (a bit of cramps, sore boobs around ovulation etc etc).

But anyway long story short I had a bit of light pink spotting 2 days ago and then today I had this. I’ve had light brown tinged discharge throughout the day but then this when I went to the toilet. Just checking it’s a normal sign that my period is on its way or if it’s anything else?

Thanks for any help! (This was dark pink but looks slightly darker in the shadow)
