Kyla • I love my daughters and sons(r.i.p)and my husband💗blood donor🩸 and milk donor🤱🏼

This was taken at 11 weeks 5 days. Ultrasound tech said she thinks boy. Hubby and some fellow ex co workers say boy a couple people say girl what do you all think? I have another ultrasound on Monday before I get my cerclage placed that day. Baby was taking a nap😂😅
