Faint line on pregmate but not FRER

Merina.

Okay. Has anyone gotten very faint lines on the cheap pregmate tests then nothing on first response? I took a pregmate yesterday and saw a super faint line. Today it’s still very faint but darker then yesterday so I got a first response and there is not even a faint line. My husband and I have been trying for over 2 years, and done 6 failed <a href="https://glowing.com/glow-fertility-program">IUI</a>’s. And these faint lines have me 👀, but after the first response I’m discouraged. Just wondering if anyone has had faint lines on the cheap pregnancy test before they got their line on first response
