Pregnant at night, not pregnant next morning?

Rachel

Hi,

I took a First Response pregnancy test last night about 8pm and I had a very faint line. I could see it without straining and so could my husband. It appeared within the correct time frame but then it disappeared in under 10 min. I decided to try again this morning, thinking that I should get a better result with first urine, but that test came back negative.

Has anyone else experienced this? Do I test again?

I'm not tracking my ovulation because I have PCOS and we're not actively "trying".
