confused.

Danielle 🐈 • Married TTC #1

So originally my period was supposed to start today, but it decided to start spotting on the 30th. and I've been spotting.. I had one day where I used one tampon

I'm usually a heavy flow

but now I'm just spotting light pink..(light cramps)

I'm so confused. ever since I was 13 my periods have always been normal and consistent. took a pregnancy test.. negative.

anyone have any advice?
