Idk if I am pregnant

Ok everyone I have a question.

My period is now over a week late. I am experiencing cramping, bloating and sore nipples. I know my period is a little irregular but I is usually never late like this. We are trying. I have taken pregnancy tests but all come back negative! 😕

Has anyone else experienced this? Or am I just over thinking this cause we are TTC? Or coil I just be getting my period just super late. I am going to see my doctor this week just curious if anyone else has had same symptoms.

Thank you
