Pregnant??

So my cycle is usually around the 18th this app said it should have been the 20th if this month. Got over excited and took a test today me and another girl see a line but I’m still not sure??? Came home to my usually routine super bath relax and mini work out since I’m trying to be more active. After my workout I had light spotting when I used the restroom. Now I’m confused if I could be pregnant or if my cycle is trying to start. I was planning to test again first thing in the am since the test I did today was around 2pm. Help!! This was after about 4 min. The line did get darker enough to see it but not dark like the test line. 🤷🏻‍♀️🤷🏻‍♀️
