Now that you’re all done with your honeymoon, what you need to do is wait for the egg to be fertilized. In the doctor’s calculation the start of pregnancy is from the first day of the last menstrual cycle of the last menstrual period. This is the “menstrual age” and it is about two weeks ahead when conception actually occurs. Fertilization of the egg by the sperms happens towards the end of the 2nd week.
There will not be any early signs of pregnancy first 2 weeks. If it sounds unusual, keep on reading. What really happens on the second week is the fertilization of the egg which happened after copulation. The ten hour journey of the sperms to reach the egg happens at this time. Out of the 250 million sperms that were ejaculated to your cervix only 400 will survive the journey, and only one will be successful to penetrate the egg cell’s membrane. It takes 20 minutes for the champion male gamete to successfully penetrate the egg.
After the sperm penetrates the egg, changes occur in the protein coating around it to prevent other sperm from entry. At the moment of fertilization, your baby’s genetic make- up is complete. Since the mother can only provide X chromosomes (XX) baby boy will be the output if the egg is fertilized by a Y chromosome from the father (XY); a baby girl for both X and X.
Cases for Twins
There are cases for which a woman carries 2 babies which are called twins. This phenomenon happens when; both ovaries release an egg, and both egg gets fertilized by two different sperms or one egg fertilized by one sperm splits into two. The babies could have the same or different sexes. They may or may not look alike (identical or fraternal twins). There are also cases when identical twins are developed and delivered attached to each other, which are called Siamese or conjoined twins. This occurs in an event called fission. This happens when an egg splits partially.
Cases for Ectopic Pregnancy
Ectopic pregnancy happens when the fertilized egg settles and develops before it reaches the uterus when it should be in the uterus. An ectopic pregnancy is not something that a woman can avoid. Cases like this occurs when the mucous membrane in the fallopian tube gets infection or other types of inflammation .
A mother who suffers from ectopic pregnancy will be feeling pains in the lower tummy and hemorrhage can be experienced. She will feel pain in the shoulder tips when she breathes. These are caused by a severe pain in the abdomen region. Some symptoms are dizziness, palpitations, diarrhea and low blood pressure.
