Pregnancy test

So my husband and I have been TTC for about a year. Began metformin with chlomid two months. I completed my first round of clomid and my period didn't come on its own. I was given medication to make my period come and two weeks later and nothing. Mind you I have been taking pregnancy tests the entire time just because I got obsessive over the fertility process. Negative test after negative test and still no period. Today makes it 14 days late and I proceeded to take another test. This test showed the 2nd line within seconds. The ending result was faint but kept darkening. I know many may say its an evap like but thats usually happens if you let it sit and read after the recommended time. Has this happened to you? My goodness, I want this so bad. I'll retest in the morning, but meanwhile I need prayers y'all.
