18 days late and BFN

Ronitra

37 TTC with one 🌈 baby already looking down on me and 5 miscarriages. I’m 18 days late on my cycle starting my cycle. I’ve gone to the doctor and had my blood drawn my progesterone levels were slightly high and I was told I would start my cycle any day. Well this past Monday 4/9 still no cycle 2 weeks late. Had to have blood work again progesterone levels are still high. This is stressing and so confusing. My cycle has been regular ever since I came off BC a year ago. Can someone give me some advice. This is annoying and I’m tired of the BFN test results.
