Advice?

So the past 2 weeks I was having some pregnancy symptoms but didn't test because I hadn't skipped a period yet, I don't think, because the month of April my period was really long. Well Monday I started my period, two heavy days and today wasn't as heavy. So tonight I took a test out of curiosity to see if I had been pregnant or not and faint line showed up. Was this a chemical pregnancy? I dont know what I feel right now.
