3 weeks late

Ch

So I took clomid for 3 months 50 mg.. well called OB in August to see what was next and she was out of the office. She didn’t get back until I was pass my cycle days to she prescribe. So I didn’t take it this month now I’m 3 weeks late period has only been this late once years ago. Went for labs today.. I don’t think I’m pregnant I don’t feel different and been feeling like AF is coming but nothing have been have some discharge. I don’t have any underlying medical conditions but we do struggle with unexplained infertility. Who has gone through this?
