most women would not even know they were pregnant until they missed their first period at 4 weeks and even then most tests dont come up positive straight away.
First babies are often felt at about 18-25 weeks, subsequent pregnancies are earlier.
Take it easy, you will be seen by a midwife at about 8-10 weeks and perhaps will get a scan at 12 weeks.
Unless you get any complications, severe pain or red blood loss then you just have to sit and wait.
Make sure you know the things to avoid during pregnancy and also ensure you take folic acid supplements until your 12 week scan.
