I’m confused..

So my period is suppose to be today and I took a test yesterday evening and there was nothing. I haven’t taken a test today because I’m just so confused on what to do. I got my mirana out on June 9th and started my first regular period again after two years and on July 4th-8th I started my period. I ovulated and peaked on July 19th. Me and my partner had enter course everyday leading up to that day and also a couple times after that day.

I have taken a couple test and they all come back negative. But my period is considered late because I haven’t started yet.

Someone help me?!?
