You are 2 weeks and 6 days

Your reproductive organs are going through complex processes that will let your body maintain the pregnancy.

260 days until your due date

If you've conceived, the blastocyst that will become your baby is getting ready to embed in the uterus lining, and the placenta is starting to form.

Another important change is also happening. After ovulation, the empty follicle turns into the corpus luteum ("yellow body"), a small fluid-filled sac that develops blood vessels and starts producing progesterone. Progesterone creates the mucus that helps the fertilized egg survive and builds up the uterus lining, where the blastocyst will soon embed.

The corpus luteum also makes a little estrogen. By about 8–12 weeks, the placenta takes over making progesterone, but the corpus luteum keeps helping with hormone production until about six months, when it usually shrinks away.

Ask a Doctor

Should I stop taking medication in case I've conceived?

Many medicines are safe, but some aren't or haven't been fully tested. These include many allergy antihistamines, over-the-counter sleeping pills, and many painkillers.

If you've accidentally taken an over-the-counter remedy that isn't recommended in pregnancy, one dose is unlikely to have done any harm. Get medical advice if you're worried.

If you need to keep taking a medicine in pregnancy, ask whether it's safe. Pharmacists know a lot about all medicines, but your doctor is the best person to ask about prescription drugs.

The miracle of conception

When you think about everything that has to fall into place for a baby to be conceived, it's amazing anyone gets pregnant. No wonder people call it the miracle of life.

To become pregnant, all of these have to happen:

Your hormone balance must be right for an egg to develop.
You must ovulate; without an egg, fertilization can't happen.
You need to have sex at the right time in your cycle. Sperm last about three days in healthy cervical mucus, and some months there may be only two or three days when you can conceive.
Your partner must produce plenty of healthy sperm that can get through your cervical mucus to the egg.
Once the egg is fertilized, the blastocyst has to implant securely in the uterus lining.
The corpus luteum must produce enough progesterone to maintain the pregnancy.

This is general information based on NHS guidance, not medical advice, and every pregnancy is different. Talk to your midwife or GP about anything that worries you. If your baby's movements slow down or change, or you have bleeding, severe pain or leaking fluid, call your maternity unit straight away. In an emergency, call 999.
