In case anyone was wondering. These pregable tests on Amazon are trash. I didn’t read the reviews well enough before buying them, and just got them because Amazon recommended them to me and it seemed like a really good deal for the amount of tests. Well, the day they came in the mail, I had not even ovulated yet so I took one as a control and it had a very convincing indent line. Every one I have taken since has been hit or miss. Some have faint lines and others don’t. I won’t know if these things are giving me true lines unless the lines progress but by then, any other test would be able to pick it up. Don’t waste your money on these, easy at home is a much better brand if you can’t see the indent, turn your brightness all the way up and click on the picture to make it bigger this app really eats the quality of pictures
