Is spotting normal in pregnancy?
Spotting is light bleeding from your vagina. It is similar to your menstrual period, but much lighter. A little spotting is common during early weeks of pregnancy. The color of blood can vary from red to brown. But sometimes, it can be a sign of something serious (miscarriage), so it is better to consult with your doctor.
Is it too early to test for pregnancy at 4 weeks?

What can ultrasound at 4 weeks show?
When you are 4 weeks pregnant, your ultrasound may only show a small circle at the center. This circle is actually known as a gestational sac. At this stage, it is not possible to see much more than the gestational sac. The gestational sac is identifiable until you are four and half weeks pregnant.
