Implantation bleeding? Or period? TMI pic!

Hello! I was 11 DPO yesterday, I started getting cramps and when I wiped I had very very light pink spotting. I put a pad on because I thought it was the start of my period and went to the store to get tampons.

The spotting has stopped, but I still have some cramping here and there. Here’s a picture of my pad this morning, just a small spot of pinkish brown blood. I inserted a tampon to see if there was any blood and there was nothing on it.

My period is due tomorrow, I have only ever had this happen to me once before a few years back. I don’t usually spot before my period, so this is definitely interesting for me. I’m probably symptom spotting and going crazy because I want a baby so badly. 😝

Has this happened to anyone before?
