Scared to test, I don't want to be let down again.

About a week or so ago, I took a clearblue plus pregnancy test and received a faint line. When it came up within seconds of taking the test, my heart dropped. I thought to myself, "this is it! I'm finally pregnant!" then received news that this has happened to many other who tested and weren't in fact pregnant. Having pcos and trying to conceive is a struggle. My mom has a gut feeling that I should test again, she feels I'm pregnant, but I don't. I'm too scared to test. I can't handle another heartbreak right now. Test after test, negative after negative, it fucking hurts. what do I do... ? 😭
