Uterine lining is preparing for a baby !!!

Day 3 of my period, thanks to Aygestin, so I went in for an ultrasound and my uterine lining is at 4mm!!!!! I am soooooo happy as you ladies can relate bc when we aren’t getting a period our uterine lining is super thick which makes it hard for the baby to implant. When we started the process my uterine lining was like 20mm!! I am sooooo happy can you tell! Lol bloodwork feedback this afternoon then I start Clomid tomorrow and a trigger shot next week! It’s baby making season !!!! #TTC 🤱🏽🤰🏽🥰
