Think I’m over testing!

AL

Been ttc for 7 years, I got my first positive test 2 weeks ago, thinking I’m 6 weeks today. I’ve tested every day because in my head I need to see it. I have strong symptoms, no bleeding. But the test this morning was a little fainter. In my last pregnancy with my daughter, the lines got fainter but of course she’s 7 now and was all fine. Has anybody else experienced lines getting fainter the more weeks go on?
