ADVICE PLEASE!!!

Hey yall! Okay, so I had a miscarriage last May and my husband and I have been ttc ever since. My period was supposed to start today but for the last 6 days I’ve been having brown/light pink spotting. It’s very light and I don’t have to wear a tampon. I use a panty liner just in case but usually just shows when I wipe. I thought at first my period was about to start but it never did. I don’t want to get my hopes up and think it’s implantation bleeding. Has anyone else experienced this and found out you were pregnant? I am so ready to have a baby and this will be our first child!
