Over-mature follicle? IUI?

I had an IUI Monday morning. Went I went in for my follicle scan on Saturday, they said I had one measuring 26 and one measuring 13. I triggered at 8pm Saturday, and had IUI at 11am Monday. I’m worried it was “over mature” based on what I’ve read, but the nurse that day said that as long as it wasn’t a cyst that existed on my day 3 scan, and it developed over the cycle, then there is no such thing as too big?

I think I’m going to save myself the stress of testing out my trigger and just wait until my blood HCG test. Wish me luck! Has anyone had success with IUI? It was just a shot in the dark to try it because my insurance covers it. My problem isn’t so much getting pregnant as it is my recurrent pregnancy loss. 😕
