It's a little too soon for pregnancy tests to be accurate. However, if you weren't using birth control, then yes there is a possibility you could be pregnant.

If you have been using the 'pull-out' method of pregnancy prevention, then, yes, you could be pregnant and farther along than one week. In which case, a pregnancy test may be accurate.

When is your next period due?

You could have the flu or another illness.

I am going to suggest that you see your doctor and ask about birth control so that if this is a false alarm, you can have better odds of this fear not re-occurring.

Around may 6

If you are pregnant it would be way too early to have any symptoms. Way, way too early. It's only been 5 days.

I suggest you wait until your next period. If it's late then get an hpt, use first morning urine as it's more accurate.

Also listen to Cats suggestion and get some form of birth control.
