Help from hpt veterans needed

Laura

I now how this is gonna sound, so let me start by saying I DO NOT have eye lines. Neither am I 21 and TTC for 2 months. That being said: HOW and WHY do I keep getting these very very faint lines at a 2-3 minute mark and they keep fading away afterwards? When they are dry they are not even there, no matter how hard I squint.

I did have those same tests last year one day before I got a clear positive at 10dpo. But this time I keep getting them for 3 months already and am NOT pregnant. I did test with different brands. Several. Ideas? Please and thank you!🙏🏻

I did check my blood hcg level to confirm I am not pregnant. Last month and the month before.
