I have a very faint line

So my husband and I have been trying for a baby. This is our 2nd cycle since starting. I was really anxious to test even though I'm not due for a period for 6 more days. I took a test yesterday and it was negative. At 4 am this morning I took another and had a faint line in the pregnancy window and my husband confirmed I'm not just seeing things. Help! Could that be anything other than I'm pregnant?
