Very Late late late

Nomi

Okay. So I have ALWAYS had regular 28 day cycles my ENTIRE period life. The only time I was EVER late was when I was pregnant with my son who is now 2. My periods went back to normal after having him. Welllllll since around February (when we started trying to have another baby) my cycles have gone from 28 day cycles to now 35 day cycles. This month I am currently 11 days late. I’ve taken pregnancy test. Negative. I went this morning for a pelvic ultrasound to make sure I didn’t have cyst on my ovaries. I’ve gotten blood work done to test my hormones. Everything was normal. No cyst. Blood work completely fine. But still no period. I’m beginning to worry. Has anyone had this happen or know why this is happening??? I tried to make an appointment with my OBJYN but he’s on vacation for 2 weeks. Pics are my cycle the past few months
