Helpppp - first period?

I thought I finally got my first pp period. I had some blood on my undies, and a light red when I wiped. So I put a pad on. And now, nothing. Literally only had the light red the one time I wiped, and my pad is practically clean still.

The only time I've ever had bleeding like this, I got a positive test 3 days later 😅

We were not trying. I'm on the pill. Hack we haven't even had sex in a while (the last time was a week ago, but he didn't cum inside me lol) and before that was a little while as well.

Has any one had their period start with just a bit of spotting first? I thought my period would come back full force (I have decently heavy, crampy 6-7 day periods normally) I'm not even cramping as bad as I used to.
