Spotting or period?

So yesterday I made a post about having belly ache and no period. I was supposed to come on my period Monday but nothing (normally I come on predicted time to the app).

So I husband said this morning oh you haven’t come on your period yet and you said it would be Monday. The minute he mentioned it when I went to the toilet and wiped it was abit pinky discharge. So I told him oh I’ve come on my period now that was at 9am it’s now nearly 1pm and since I’ve been to toilet there’s been nothing on tissue and nothing on my pad. And no more belly ache??? I’m confused
