Needing a little advice!

Needing a little advice ladies! 

My "period" came on 5 days late on the 2nd with no cramps (I always get bad cramps) and only lasted until about mid day on the 3rd. My periods usually last about 5 days for me so this was very strange and almost just seemed like spotting. I feel like I've had multiple pregnancy symptoms leading up to the day I started and it's continued past it. When I was pregnant last year and miscarried I also had this late, very short period and didn't even know I was pregnant until I miscarried.. so now I'm not sure if I should waste my money on a test or not. Maybe just for a peace at mind? Let me know what you guys think? Has this happened to anyone else?
