The second week of pregnancy also occurs before you conceive. It is usually around the second week (day 10-14 following the beginning of your last menstrual bleeding) that ovulation occurs. Conception, the process through which your egg and your partner’s sperm fuse to form the beginnings of your new baby, occurs up to 24 hours after ovulation. Assuming you ovulate on day 14, conception will usually occur on the first day of the third week since the start of your last menstrual bleeding. Some women have a shorter cycle and will ovulate before day 14, in which case fertilisation will occur in week 2. At the beginning of week 2 your womb and ovaries are still doing all the preparations which make fertilisation and implantation of the fertilised egg into the wall of your womb possible.
In week 2 of pregnancy your body is making the many necessary preparations for ovulation and conception. Stimulated by luteinising hormone the single egg from which your baby will grow is maturing in your ovaries and your womb is developing a nutrient rich lining that can sustain that egg following fertilisation. Find out about all the unseen changes which occur in the lead up to ovulation.
