Question for pregnant women

Have any of you ladies ever experienced what you thought was your period in your early pregnancy? I had so many symptoms of pregnancy including late period, but I got my period 5 days late. It just felt different though. It didn't feel like my normal period, there was just bleeding. It was a little bit lighter than my normal period too. And now that it's gone I still feel like I have some pregancy symptoms- exhausted all the time, heartburn (which I never usually get), enlarged breasts etc. I didn't take a test because I figured I'm not pregnant if I got my period. But if my "period" could've been something else, then it is a possibility. Has anyone experienced something like this before?
