Possible period?

I know the title is odd. I’m 20 years old and ttc. I have been trying for 4 months and I know it’s not a lot. But I have PCOS and my periods have been surprisingly regular since stopping birth control. I get a period every month maybe a few days off but haven’t skipped a month In a while. I test with ovulation strips every month and the past few months I’ve been having peak ovulation tests. I wasn’t thinking anything of it but the other day I got extremely dizzy at work. I got dizzy today while sitting down in the car. I have had sore boobs which I sometimes get before my period so I can’t really say that’s a symptom of possible pregnancy,But I started spotting yesterday. Light brown and no even enough to have to wear a panty liner. There’s barely anything on the toilet paper when I wipe. I haven’t ever had this happen not once. My “period” started 2 days sooner than expected but I have been feeling extremely tired and just having no energy what so ever. Should I test or wait to see if my period starts?
