If you have not had a preconception test before you get pregnant, you will need to have the following tests done after you get pregnant: 1. Ultrasound to find out if the size of the gestational sac matches the number of days of menopause, and if you can see the germ and the primitive heartbeat in the corresponding week of pregnancy. 2. Blood tests will be done to find out if progesterone and estradiol are normal, and to find out if HCG is normal. 3, The blood tests should also be done to determine the blood type and thyroid function to see if the thyroid function is normal. 4. routine leucorrhoea tests should be done to see if there is inflammation in the vagina and, if necessary, cervical cancer screening to see if there are epithelial lesions or other lesions in the cervix.
