This is a study of the feasibility of a translational research clinic for pregnancies conceived by in vitro fertilisation (IVF). A group of at least 120 pregnancies (of which, at least 80 IVF-conceived) will be followed from early pregnancy to delivery, in order to gain early insights into the growth of the baby before birth, the physical and emotional adaptation of the mother to the pregnancy and how the placenta works. The investigators will collect preliminary data on how these factors may differ between pregnancies conceived with and without IVF, and between different IVF treatment modalities such as fresh or "frozen" embryo transfer IVF. The study aims to understand the practicalities of such a clinic, to identify barriers to participation in the clinic, to assess the uptake of different research measurements and to identify key measurements/time points with the greatest potential to identify and understand the origin of fetal growth and maternal adaptation differences after IVF conception in a full scale study.
