My last ultrasound before my FET on 7/2

Lilita • IVF in July successful 1st time 🙏🏽 excited ready to be a mother because I know God is protecting us due 3/20/21 but had my son 2/28/21 my sunshine ☀️ 💙👶🏽 🙏🏽🇭🇳🇩🇴🌈🤰🏽

So my doctor said my lining was 9mm she said it was perfect but can it get thicker in a week?
