Yes, sometimes a woman may feel more tired (asthenia), with nausea, breast tenderness, mild abdominal pain, and may even have a little bleeding (implantation bleeding). However, no symptom can be associated 100% with pregnancy, and likewise, if the patient has no symptoms it does not mean she is not pregnant. Each woman will react differently.
In the case of assisted reproduction treatment, these symptoms can also be related to the medication the patient is taking.
The important thing in this case is to follow the guidelines of her doctor and wait about 12-15 days after the embryo transfer or insemination to do the pregnancy test which should preferably be done in blood.
