Wait or test?

Ok ladies so Glow said my period was supposed to start yesterday but i haven't been logging like i should be so i counted my days again and used 3 online calenders and my period was actually supposed to start 3 days ago! And my period is like clockwork missing at most 2 days(Ive got my fingers crossed that she doesn't show, I even feel making this post could mess me up😒🤦) But I feel like my symptoms are all in my head. Like I get nauseous for like 2 min then its gone and cramps on my left side that come and go. Also what I believe was implantation bleeding. Has anyone else experienced this? Were you pregnant? Should I wait longer to test or take a test now? Thanks!
