TWW is killing me

Spring
My husband talked me into doing one last <a href="https://glowing.com/glow-fertility-program">IUI</a> which we did on my cycle day 16. My period is due on the fourth. I am trying not to get excited and not to test because I've had all kinds of symptoms before and never any luck, I get my hopes up just to get heartbroken again. A week after the <a href="https://glowing.com/glow-fertility-program">IUI</a> they said my progesterone level was 45.8. Yesterday and the day before 8-9DPO I had sharp pains in my uterus, different places. Today I felt slightly nauseous before I ate my breakfast and my oatmeal tasted different, plus my shower curtain smelled really midewy which I never noticed before. It could be its just more humid right now. I can analyse everything for or against. Is anyone else experiencing this?
