I posted this 5 other times and had no responses! Please help!!

I am 6 days late. I didn’t have sex the last time I was ovulating but I did have sex multiple times the time before that. I took a pregnancy test when I was 2 days late and it was negative. I took another one when I was 4 days late... another negative. I have a ton (!!!) of watery discharge and I’ve had that for about a week and a half. My breast’s are tender and there is no sign of aunt flow coming any time soon. Has anyone else been through this? I don’t know whats going on.
