Doesn't feel real

Just got a super faint line on a cheapo and it's only cycle day 19 for me, period is due in a week. Must have ovulated early this month to have a positive at 2 weeks 5 days! I had a miscarrage in May at 7 weeks so I am super nervous, and now wish I would have waited a week to test because then I would be a week farther! But my boobs are feeling super sore and I was nauseous all day so I figured I would try. I'm going to take an early detection test first thing tomorrow morning for confirmation but a line is a line!
