Confusing pms symptoms - is this normal?

So I did a poll on here yesterday but just want to come back and update. I’m on cycle day 31 currently and have irregular cycles that can be anywhere from 30-50 days so I’m never too sure if my pms symptoms are normal!! But I do think I ovulated about 10-15 days ago so my period is expected soon.

Yesterday I experienced this spotting (see picture) in the morning when I went to the toilet it was dark pink and watery. I’d been having light brown spotting for the last couple of days before it. When I saw the dark pink, I assumed my period would come the next day!

But today, I’ve just been back to the light brown spotting, which is much less in consistency than the dark pink. I’m so confused!! I know light brown spotting is a pms symptom, but surely it should be increasing in consistency over time? Is this normal, has anyone else had it?

Thanks for any help in advance!
