Pregnancy advise

Okay so am looking for a little bit of advise.

We are trying for a baby and have been now for 2 years.

The past few days I have had really sore boobs and have been sick. Of course I know this could be symptoms that my period is due however I am hopping I could be pregnant.

My period is due in 6 days would it be too early to test?

What did you notice when you were pregnant, did you have implantation bleeding?
