A: You don't have to lay down because the cervix doesn't remain open, but most doctors let patients lay down on the table for 15-30 minutes after the procedure.
Q: Do I need to take it easy after an IUI?
A: Most people don't need to, but if you had cramping or don't feel well afterward it makes sense to take it easy for awhile. Some people reduce their aerobic activity and heavy lifting during the luteal phase in hopes it will increase the chance of implantation. It is more important to take it easy for a bit after IVF, as that is a more invasive process.
