Faint line

Ok so I’m wondering if I should be disappointed or get excited ugh. This morning (well around 10:30) I took a test, I instantly noticed a faint line. I was so excited and nervous that I said I’m going to take another one, but then it shows “not pregnant” I’m confused. Should I be disappointed? I been TTC since March 19th so not even a month so i know it’s early. Plus i don’t have periods regularly so I never know when I’m ovulating anyways so I can’t go off my Last period because it’s been a long time. My body has always been this way since my first Boy (which was 4 years ago) sooooooo I need suggestions. 😰
