2 Weeks Pregnant

At 2 weeks pregnant, you haven't conceived yet. Pregnancy is counted from the first day of your last period, and week 2 is the lead-up to ovulation, when one of your ovaries releases an egg. In a 28-day cycle that is usually around day 14, but many people ovulate earlier or later. This is the most fertile time of the month. In a US study of 221 women, the chance of pregnancy rose from about 1 in 10 for sex five days before ovulation to about 1 in 3 on the day itself. This page covers why no test or scan can show a pregnancy yet, what stomach twinges mean now, and hCG levels.

What trimester is 2 weeks?

Week 2 is in the first trimester, which runs from week 1 to week 12. The second trimester starts at week 13, 11 weeks from now.

  • Week 2 — first trimester, month 1; 38 weeks to go until your due date.

How big is your baby at 2 weeks?

There’s no measurable baby yet at week 2. Pregnancy is counted from the first day of your last period, so the earliest weeks happen before conception even takes place.

Baby development at week 2

Still no embryo this week — your body is gearing up to ovulate. The lining of the uterus thickens to prepare for a possible pregnancy, and an egg matures inside its follicle. Around the end of this week (day 14 in a textbook 28-day cycle), ovulation releases the egg into the fallopian tube, where it can be fertilised over the next 12–24 hours. This is the most fertile point of your cycle.

Can a test or scan show pregnancy at 2 weeks?

By the usual count, no. Week 2 comes before conception, so a test will be negative and a scan has nothing to show. Home tests react to hCG, a hormone the body makes only once a pregnancy has started to implant in the womb.

If you mean 2 weeks after conception, you are about 4 weeks pregnant and your period is due. Many home tests can give a result from the first day of a missed period, but not every pregnancy shows up that early. A US study estimated that about 1 in 10 pregnancies had not yet implanted on the first day of the missed period, so no test could have found them that day. One week later, that fell to about 3 in 100.

A blood test at a clinic can pick up hCG sooner than a urine test. An ultrasound is not useful yet. On a vaginal scan, the first visible sign of pregnancy is a small fluid-filled sac in the womb, and it usually shows up at about 5 weeks.

Your body at 2 weeks

  • Clear, stretchy, egg-white cervical fluid near ovulation
  • A slight rise in basal body temperature after ovulation
  • Mild one-sided ovulation twinge (mittelschmerz) for some
  • Higher libido around ovulation

How your stomach feels at 2 weeks

Any twinges this week come from your cycle, not from a pregnancy. Around ovulation, some people get ovulation pain: a dull ache or a sudden, sharp twinge low in the belly, usually on one side. The NHS says it can last from a few minutes to a day or two, and often switches sides from month to month. Bloating, tender breasts and light spotting are other common signs of ovulation.

Ovulation doesn't always fall on day 14. Most people ovulate about 10 to 16 days before their next period, so the timing moves with your cycle length. Get medical advice if the pain is severe and painkillers don't help, if it keeps coming back, or if you think you could already be pregnant.

Tips for week 2

  • If trying to conceive, time intercourse for the few days before and on ovulation
  • Keep taking folic acid daily
  • An ovulation predictor kit can help predict your most fertile days

2 Weeks Pregnant: your questions

What trimester is 2 weeks?
Week 2 is in the first trimester, which runs from week 1 to week 12. The second trimester starts at week 13, 11 weeks from now.
How many months is 2 weeks pregnant?
2 weeks pregnant puts you in month 1 of pregnancy. Month 1 covers weeks 1 to 4. Providers count in weeks; months are approximate.
Is there a baby yet at 2 weeks?
Not in the way you'd picture. Pregnancy is dated from your last period, so weeks 1–2 happen before conception and week 3 is when fertilisation occurs. There's no measurable baby to picture yet — but the foundations are being laid.
What are hCG levels at 2 weeks pregnant?
At 2 weeks from your last period, there is no pregnancy hCG to measure, because conception hasn't happened. The hormone only appears once an embryo starts to attach to the womb. If you mean 2 weeks after conception, you are about 4 weeks pregnant. Cleveland Clinic's chart puts typical levels at that stage between 5 and 426 mIU/mL, and a level above 25 usually means pregnancy. Normal results vary so much that the rise between two tests a few days apart matters more than any single number.
Can you be 2 weeks pregnant and have a period?
By the usual count, yes: your last period is part of the first 2 weeks, because pregnancy is dated from its first day. After conception, though, true periods stop, because pregnancy hormones keep the womb lining in place. Some people have a very light bleed around the time their period is due, called implantation bleeding, and mistake it for a period. Once you know you're pregnant, mention any bleeding to your provider, and ask for urgent advice if it is heavy or painful.
Does 2 weeks pregnant mean 4 weeks?
It can. Pregnancy is dated from the start of your last period, which is about two weeks before conception. So if you conceived 2 weeks ago, you are about 4 weeks pregnant by the usual count, and that is the number your provider and your due date are based on. The time since conception, sometimes called fetal age, is about two weeks less than the pregnancy week. A dating scan later on gives the most accurate age.
Can you be nauseous at 2 weeks pregnant?
Not because of a pregnancy. At 2 weeks you haven't conceived, and even 2 weeks after conception it is early for sickness. In a UK study of 363 pregnant women who kept daily diaries, nausea started on average 39 days after the last period, which is between 5 and 6 weeks. Feeling sick at 2 weeks is more likely to have another cause, such as a stomach bug. If you can't keep fluids down for a day, get medical advice.
