Positive line after double check

I have been taking test after test hoping like hell i'm pregnant.... everyone for the last week (since glow said my period was due) has been negative. The my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> app said i was due today.... no period.... i took a test early this morning and again this evening and didnt even wait the 3 mins as nothing showed and id lost hope after a week of testing. I just double checked them and the 2 from today now have very faint positives! Has anyone had this happen and been pregnant??? Im so hopeful but then very wary after having 2 miscarriages.... what do you think??
