Bleeding Question 🔴

L̽

So period was supposed to start yesterday. Took one the day of and today both Negative. But this afternoon I wiped after urinating and had noticed bright rose pink blood on the toilet paper. I assumed it was the start of my period since it was due yesterday. I was out of tampons so I threw a pad on and went on my day. However my pad is dry and I didn’t notice anything after I went to the bathroom the 2 and 3rd time today. Could this be implantation bleeding or maybe a miscarriage? My breasts were sore the past week but aren’t as bad today. Still very bloated though. Idk. Thought to get some feedback here. Thanks 💕
