Your baby is the size of a Fertilized Egg. Discover exactly what is happening to your body and your baby this week.
Week 2 in detail
Around mid-cycle an egg is released. If sperm meets it, the fertilized cell starts dividing as it travels the fallopian tube. You will not feel that. A test this week is almost always negative even if conception happened.
Estrogen peaks. Cervical mucus can turn clear and stretchy (egg-white). Some people feel a one-sided twinge (mittelschmerz). That is ovulation, not implantation.
Time intercourse around your fertile window if you are trying to conceive. Keep folic acid going. The checklist above covers tracking mucus and timing — this card is the why, not another to-do list.
A general guide, not medical advice. Scan timing and symptoms vary — ask your clinician.
