2 weeks pregnant
At 2 weeks, you are still not pregnant, because pregnancy is counted from the first day of your last period. Ovulation, when an egg is released, often happens around the end of the second week, and conception is most likely around that time.

Pregnancy weeks start before conception, so there is no embryo to measure yet.
What is happening in your body
- No embryo has formed yet. In the standard way of counting, the first two weeks happen before conception, while your body prepares for a possible pregnancy.1,2
- Toward the end of the second week, an egg is often released from one of the ovaries. This is ovulation, and it's the time you're most likely to conceive.1,3
- After ovulation, the opened follicle becomes the corpus luteum. It releases progesterone, which helps prepare the womb lining for a possible pregnancy.3
- Occasionally more than one egg is released. If more than one egg is fertilized, it can lead to a multiple pregnancy, such as twins.4
Changes you may notice
Everyone’s experience is different. You may notice some of these, or none.
- Ovulation usually happens around 10 to 16 days before your next period. In a regular 28-day cycle, that's around day 14, but it is earlier or later if your cycle is shorter or longer.4,5
- Around ovulation, some people notice that vaginal discharge becomes thinner and stretchy, a bit like raw egg white.4
- Sperm can survive in the fallopian tubes for up to 7 days after sex. That means sex in the days before ovulation can lead to pregnancy, not only sex on the day itself.4
Care around this week
- If you're trying to conceive, a daily folic acid supplement of 400 micrograms is recommended. The CDC says to start at least 1 month before conception. The NHS says ideally 3 months before, then continue for the first 12 weeks.6,7
- A higher dose of folic acid is recommended for some people, for example after a previous pregnancy affected by a neural tube defect. In the US, the CDC recommends 4,000 micrograms a day in that case. In the UK, the higher dose is 5 mg, prescribed by a GP, and it's also advised for people with diabetes or who take medicine for epilepsy or HIV.6,7
- In the UK, a 10 microgram vitamin D supplement is recommended in pregnancy between early October and late March, or all year for some people. Avoid supplements containing vitamin A (retinol), including cod liver oil, when you're pregnant.7
Questions to ask your provider
- How can I tell when I'm likely to ovulate if my cycle is irregular?
- Do I need a higher dose of folic acid?
- Should I take any other supplements, such as vitamin D, while trying to conceive?
- How long should I keep trying before asking about fertility support?
Questions about 2 weeks
Can I take a pregnancy test at 2 weeks?
Not yet. Conception may not have happened, and most tests work from the first day of a missed period. If you don't know when your period is due, test at least 21 days after unprotected sex.8
When am I most fertile?
Around ovulation, which in most people happens around 10 to 16 days before the next period. In a regular 28-day cycle that's around day 14, but shorter or longer cycles shift the timing.4
