I hope this spotting is what i think!!! Help

Me and my husband have been TTC for about a year give or take. I have the most normal period. I always start on time its always 4 days. According to the calendar I should be starting tomorrow, three days ago I thought I started. There was two very small brown spots, so I went on with my day and next time I went to the restroom I was expecting to get a tampon out there was nothing and two days later still nothing... I have never spotted and didn't start my period a few hours later. Please someone tell me this could be good news!!!
