You’re now 2 weeks pregnant, but still, there is no baby yet! This week you will finally release a mature egg that carries half of the 46 chromosomes needed to make your baby, and you will need to wait for the 23 chromosomes carried by the sperm.
2 Weeks Pregnant: Ovulation phase and ovulation
Your menstrual cycle is divided into four main phases – the menstrual phase, the proliferative phase, ovulatory phase and the luteal phase.
When your menstrual cycle begins on Day 0, the follicular phase also commences. Follicular phase lasts for about two weeks and is divided into two parts – the menstrual phase and the proliferative phase. The menstrual phase comes first, and the proliferative phase after. The proliferative phase (and the follicular phase) ends on Day 13 and refers to the period in which the ovary produces estrogen to prepare the uterus for a pregnancy. When a mature egg is released from the ovary on Day 14, ovulation occurs.
Remember the pituitary gland in the brain that releases the pituitary hormone, which in turn leads to the secretion of the follicle-stimulating hormone (FSH). During ovulation, your pituitary gland also releases another hormone called the luteinizing hormone (LH).
What happens goes like this:
- The pituitary gland produces FSH.
- The FSH stimulates the follicles.
- The follicles produce estrogen.
- The hypothalamus in the brain notes the high levels of estrogen and responds by producing the gonadotrophin-releasing hormone (GnRH).
- The GnRH prompts the pituitary gland to release LH.
- The LH turns the follicle into the corpus luteum, triggering the start of ovulation – the maturation of the egg.
Ovulation refers to the process in which follicles (immature eggs) emerge from your ovaries to become ova, mature eggs that pass through the fallopian tubes.
If you chart your own basal body temperature, the lowest body temperature recorded will be your ovulation day, the day when most women become pregnant the most easily.
From ovulation to fertilization
Women are born with about 2 million eggs in them. However, after puberty, some women only have about 300,000 eggs left. Although the FSH and LH stimulate about 15 to 20 eggs, only 1 will emerge as the mature egg ready for fertilization – the rest stop growing and die.
The egg you produce will become a fertilized egg next week. As of this week, you’ve completed the follicular phase and the ovulation phase. You’ve ”done your part”, so you only have to wait for the sperm to arrive and for the miraculous fertilization to happen!
2 Weeks Pregnant: No adverse effects from taking medication and X-rays
Medication taken before or during Week 1 and 2 of pregnancy usually does not have any effect on both mother and embryo. Although the medication taken is usually expelled from the body within one to two days, the embryo is easily affected by medication from the 2nd to the 4th month of pregnancy, as this is the period when internal organs begin to develop.
Certain medications can increase the risk of developmental abnormalities or bring harm to the embryo. After your gynecologist has confirmed that you’re pregnant a few weeks later, be sure to check with the doctor before buying any over-the-counter medications!
2 weeks pregnant: Ready, set, go!
When a woman’s egg and a man’s sperm meets the next week, fertilization occurs. An egg can stay alive for about 24 hours; a sperm for about few days. When the two exist in the same time frame, there is a 20 to 30% chance of a successful fertilization! Talk about beating all the odds!
Soon, you will be at the starting line of pregnancy, and it will be a long, at times difficult, trying but wondrous 9-month journey until you meet your baby. Hang on tight, and let the journey begin!
