IUI due date

Kylie

Ok, bare with me here but I have a serious question.

My husband and I had <a href="https://glowing.com/glow-fertility-program">IUI</a> done on March 16. I am pregnant 🤰🏻 🥰 however I am wondering exactly how far along I am. I know with natural pregnancies they calculate this by the first day of your last period (mine was the 29 of February, 30 day cycle). I guess I’m wondering if I’m 3 weeks along or 5. Anyone know??
