It takes about 2-3 days for the fertilized egg to enter from the fallopian tube to the uterine cavity for implantation. The fertilized egg starts to grow and develop on the endometrium after it has found a suitable location. It is advisable to have a blood test after implantation to see if the blood HCG has started to rise. It is advisable to enhance nutrition and protein in the diet after implantation. Drink a glass of milk every day, eat more fish, vegetables and fruits, so that the nutrition can be balanced and more conducive to the development of the embryo. It is advisable to have an ultrasound examination after 50 days of menopause to see if the size of the gestational sac matches the number of days of menopause.
