7 days after embryo transfer
After the puncture procedure of the female gonads, 3-5 days pass and one of the most important moments comes - the transfer of the embryo into the uterus. The implantation of a diploid cell into a woman's body takes no more than 5-7 minutes, but the success of the IVF procedure will depend on the correctness of the manipulations performed, the quality of the blastomeres and the patient's behavior.

7 days after conception - signs of pregnancy
The first signs of pregnancy appear within 10-14 days after the successful implantation of the diploid cell into the endometrium. Embryo implantation is preceded by hatching, during which the blastocyst leaves the protein shell and immerses itself in the uterine wall. This process may be accompanied by the evacuation of mucous discharge from the vagina and a small amount of blood.
Signs of pregnancy:
- Drawing pain in the abdomen
- Lack of appetite
- Frequent urination
- Bloating
- Emotional lability
On the seventh day after the IVF procedure, the implanted embryo begins to actively develop. This is evidenced by the excessive production of human chorionic gonadotropin (hCG). Changes in hormonal levels can affect a woman's overall well-being.
1 week after embryo transfer – sensations
On the fifth day after the transfer of the diploid cell, discomfort in the abdominal area may increase. The process of gastrula implantation into the endometrium may be painful and accompanied by minor bloody discharge.
The severity of pregnancy symptoms is determined by the stages of embryo development after transfer into the uterine cavity:
- 1 day The membrane around the blastocyst ruptures and it comes out for further implantation into the loosened endometrium.
- Day 5 Gastrula grows into the endometrium and begins to receive nutrients from it.
- Day 2 The fertilized egg touches the wall of the uterus and prepares to penetrate the mucous membrane.
- Day 6 The primary formation of the placenta and the tube connecting the fetus to the mother's body occurs
- Day 3 The blastocyst implants and penetrates into the soft tissues of the reproductive organ
- Day 7 The embryo begins to secrete hCG, stimulating further intrauterine development
- Day 4 The formation of germ layers occurs, after which the blastocyst turns into a gastrula

7 DPT – test
The first significant hCG surge is determined on the seventh day after IVF, but its concentration is still too low to judge the success of the procedure. In 90% of cases, specialists refer patients for hCG analysis on the 14th day after embryo transfer.
In case of successful embryo transfer, the specialist determines the concentration of the hormone in the mother's body. This allows for an accurate calculation of the optimal course of pregnancy management, taking into account the use of hormonal drugs. On the 25th day, the woman goes for an ultrasound, which determines the location of the fetus and its condition.
The likelihood of successful conception depends largely on the behavior of the patients themselves.
Также рекомендуется нормализовать режим сна и бодрствования, обеспечив полноценный сон продолжительностью от 8 часов. Соблюдение простых рекомендаций повышает вероятность успешной имплантации и проживания эмбриона на 30-40%.
To maintain pregnancy after IVF, you should:
- During the first day after the procedure, stay in bed.
- Eliminate foods that cause flatulence from your diet
- Lead a sedentary lifestyle for 1-2 months
- Avoid sudden bends and car trips
- Reduce physical and emotional stress to a minimum
HCG Analysis - Rules for Delivery
The concentration of hormones in the body of the expectant mother is determined by taking venous blood. Reproductive specialists recommend taking tests in the morning on an empty stomach - at least 8-9 hours should pass between the last meal and blood donation. If a woman takes over-the-counter drugs, she should inform her doctor about this a few days before the tests.
Enzyme immunoassay should be performed not only to determine gestation. The hCG test should also be taken in the 2nd trimester of pregnancy in order to identify developmental defects in the child. Correction of supportive therapy can prevent up to 25% of congenital pathologies and anomalies.
Conclusion
On the 7th day after embryo transfer, patients may complain of nagging abdominal pain, mucous discharge from the vagina and malaise. Symptoms indicate implantation of the embryo in the uterus and production of hCG. Pregnancy tests are performed only on the 14th day after IVF, which is due to the relatively low concentration of the hormone in the blood.

Features of in vitro fertilization
In vitro fertilization is a modern reproductive technology used for infertility. During the procedure, an oocyte is removed from the ovaries and fertilized in vitro. After that, the diploid cell is cultured in a special incubator for 3-5 days.
At what point to transfer the embryo to the uterus is decided by the reproductive specialist, based on the degree of readiness of the endometrium for implantation. It is believed that five-day embryos take root better, but not all fertilized oocytes can survive until the transfer at the appointed time.
