some tests can tell you five to seven days before your next missed period
Fertilization would be when conception occurs, if the fertilized egg implants itself in the uterus lining this is when pregnancy occurs and thus the menstrual cycles stop. Although fertilization doesn't always result in pregnancy, and pregnancy can miscarry at any point.
If it is outside the female body, it is called in vitro fertilization. If it occurs outside the uterus it is called an ectopic pregnancy.
The hormone known as the "pregnancy hormone" is human chorionic gonadotropin (hCG). It is produced by cells formed in the placenta after implantation occurs. hCG is the hormone detected by pregnancy tests to confirm pregnancy.
Fertilization in cats typically occurs in the fallopian tubes, where the sperm meets the egg after mating. The fertilized egg then travels down the fallopian tube and implants in the uterus to develop into a pregnancy.
Fertilization of the egg typically occurs in the fallopian tube, where sperm travels to meet the egg released from the ovary during ovulation. The fertilized egg then moves down the fallopian tube to the uterus, where it implants to develop into a pregnancy.
external fertilization
Nobody feels anything when fertilization first occurs. The pregnancy symptoms are more than a month away.
Implantation typically occurs about 6-12 days after fertilization when the fertilized egg attaches to the lining of the uterus. This marks the beginning of pregnancy.
When sperm fuses with egg it is called fertilization .
Implantation typically occurs between 6-12 days after fertilization, but can happen as late as day 14. If implantation occurs beyond this timeframe, it may result in an ectopic pregnancy.
The ovaries produce eggs and hormones such as estrogen and progesterone. During the menstrual cycle, the ovaries release an egg for potential fertilization. If fertilization occurs, the ovaries continue to produce hormones that support pregnancy.
This process is called in vitro fertilization (IVF). The mature egg, along with sperm, is fertilized in a laboratory dish. Once fertilization occurs and the embryo(s) develop, they may be transferred back into the uterus for implantation and pregnancy.
