We’ve gathered pregnancy test photos from real customers who began testing with Natalist’s early result at-home pregnancy tests after IVF to share examples of what a positive test may look like.

Let’s review what happens after an embryo is transferred into its home for, hopefully, the next nine months. At the time of a transfer, the embryo is already usually a five day old blastocyst who beat the odds in the lab. After the embryo has been transferred, it takes a few days for the embryo to hatch out of its shell and implant into the uterus. By the fifth day, implantation should be complete, and your body will begin producing the pregnancy hormone (hCG) from cells in the developing placenta.
According to NYU Langone Fertility, the following occurs each day after transfer:
- Day 1: The blastocyst begins to hatch out of its shell.
- Day 2: The blastocyst continues to hatch out of its shell and begins to attach itself to the uterus.
- Day 3: The blastocyst attaches deeper into the uterine lining, beginning implantation.
- Day 4: Implantation continues.
- Day 5: Implantation is complete. Cells that eventually become the placenta and fetus have begun to develop.
- Day 6: Human chorionic gonadotropin (hCG), the hormone that signals a developing pregnancy, starts to enter the bloodstream.
- Days 7 and 8: Fetal development continues, and hCG continues to be secreted.
- Day 9: Levels of hCG are now high enough in maternal blood to detect a pregnancy using a blood test.
