Estradiol level day 12

Sara • Momma to AAG 🧒🏻 💙 & CDG 👶🏻 💙

Hi all, third IUI today. Got my Estradiol level back. It was taken yesterday right before my ultrasound where they saw a big follicle and they gave me my trigger. It came back at 47.8. Does this seem low for this part of the cycle? I plan to ask my doctor but wanted to get opinions here. This is our last try before IVF. Any insight would be helpful.
