Implantation bleeding or period? So confused!

I’ve been trying to conceive after a miscarriage for about 2 months now. I had some bleeding 28 days ago but it was very odd. It didn’t seem like a period to me. Anyways I’ve been having several symptoms of early pregnancy symptoms including nose bleeds which I only have when I’m pregnant. Well I just went to the bathroom and when I wiped there was a little blood on the tissue (a watery brownish color). I washed my lady bits and wiped again and it got darker red and a little heavier but still light. I’m not sure if this is my period or implantation bleeding. I’m so hoping im pregnant but i guess if this is my period it could be good to because at least I’ll know that I’m regular again after miscarrying and I can track it better. I guess what I’m asking is how does implantation bleeding work and how do I know if this is that or my period? I’m so sick of not knowing how my body works.
