Implantation????? HELP

Nayeli • My name is Nayeli! | California | MUA |
I don't really know anything about this. I discharged something like brownish on the 20th and I was suppose to start my period on Monday which was the 22nd but I didn't think nothing of it bc I thought it may be my period. My boobs haven't been sore, I've been really thirsty lately and tmi gassy... Haha but idk... Please help. FYI still haven't gotten my period!! Baby dust 😊☹😥👶🏻 What should I do?? I don't want to take a test bc I'm scared it'll say negative since I always get that! Been trying for 4 months
