Period issues.

Ok ladies I haven't been on here in forever lol but i have a question =) I was supposed to start my period on monday, but on tuesday i had slight cramps and only a light pink blood when i wiped. wednesday again just blood when i wipe and today i have just very mild cramping and only blood when i wipe but it is a little bit redder today. do you think i could just be having a light period or could i pregnant? I am a little afraid to test because i did have a miscarriage two years ago and I feel like i would just almost not want to know and if it was another miscarriage then I would just like to think it was a period. idk what do you guys think?
