Y’all I hate waiting.

I didn’t have this with my first child so I’m just wondering if this is implantation bleeding. My period is supposed to start in 4 days. I have had period cramps for over a week. I know the best time is to wait to see if you miss your period but i read whoever has implantation bleeding that they normally test sooner? The first pic was 2 days ago and the second was just now.
