Lh surge?

Pa
A few months ago I tried usuing ovulation tests, but never seemed to get more than a faint line. I had stopped using birth control a couple months before that (after using for 10 years), so I just assumed my body hadn't adjusted yet. I was so bummed out that I gave up until a local store was closing and had the Answer ovulation+pregnancy test kits for $4. I can't pass up such a great deal, so I figured I would give it another shot. So....is this a surge? The lines have been faint for almost a week now. The test line has a really dark strip, but is then a little faint close to it. Should I test again tonight to make sure?
