Once the IVF process is complete, the body reacts in the same way it does to a normal pregnancy. It takes several days for a fertilized egg to implant in a women's uterus and begin emitting hormones in large enough amounts to be detected in a pregnancy test, notes Shady Grove Fertility. During the two-week waiting period, it is recommended that women act as if they are pregnant by eating healthy foods and avoiding alcohol, caffeine and smoking. Pregnancy tests performed by a doctor are always more reliable than home pregnancy tests.
