The second week of pregnancy is exactly one week after the start of the last menstrual cycle. During this week, the body is preparing for ovulation. The uterus, which just shed the lining from the previous cycle, has started to build up a new lining, in hopes of providing a place and nourishment for a fertilized egg. Luteinizing hormone surges during this week as it prompts the ovaries to prepare to release a mature egg. Estrogen levels rise, causing the cervical fluid to become fertile. The cervical fluid goes from a creamy consistency, to clear and stretchy, egg white like. This is the best cervical fluid to help the sperm to get up through the uterus and into the fallopian tubes to wait for the releasing of the egg.
The cervix is preparing too. The cervix goes from being low, firm, closed to soft, high, open, and wet. This is referred to as SHOW – soft, high, open, and wet. This helps the sperm to enter into the uterus and the fertile quality cervical fluid always accompanies SHOW. The libido picks up, because ovulation means procreation is possible, nature has a built in libido to increase during ovulation so you will want to have sexual intercourse.
Continue with proper nutrition, taking prenatal vitamins and practicing good habits. Start having sexual intercourse every other day to every single day all this week. A normal cycle will have ovulation occurring at around day 14, which is two weeks after the first day of bleeding of the last menstrual cycle. Some woman may ovulate sooner than day 14 while others may ovulate much later. The key to a successful conception is to make sure sperm are present in the fallopian tubes when the ovaries release an egg.
Sperm can live up to five days in good fertile quality cervical fluid. The egg only lives for 12 to 24 hours, so it is best to have sperm present when ovulation happens for the best chance at pregnancy. The only way to figure out exactly when ovulation occurs is to chart the fertility signs, either basal body temperature, checking cervical fluid and cervical position and or with ovulation predictor tests and monitors.
