Question ? Spotting

Lizette

So this is what my 📆 looks like ! Last night I went to the restroom 2 pee & when I cleaned I had very very light pink blood super light and then that was it I taught my period was coming , so today in the morning I wiped and I didn’t see anything so I decided to clean a little deeper inside not to deep just slightly if I can explain right lol and I had very light pink blood also very light , my period is due tomorrow is this my period starting slow ? Or what could it be ? Me preg test as of the day before yesterday was negative on first response !!
