Confused and hopeful

So you know that bloody-sticky discharge that isn’t red red? Like right before you start your period? Well I had that yesterday morning for about half the day. My boobs hurt and I’m a week and a couple days to early to start my period. I’m usually on the penny to start or at least closer then this. I usually get it after 24hrs from having that odd discharge. Like it just transitions into straight period blood. It doesn’t just disappear. Well it stopped about 5 last night and my period still hasn’t started. I’m not sure what to think. It’s nearly 7 now and still nothing. I’ve had slight cramping as well today and yesterday. Could this have been implantation bleeding?? I found a picture off google that is closest to what it looked like maybe mine was a little browner actually. What do you all think????
