So confused!

Courtney
Hello PCOSers, I was diagnosed with this about three months ago and have been TTC with no luck for the last year. But I was so sure this was our month, I had early symptoms and everything took a test yesterday morning and there was a faint line, even people on here saw it! Now I took another one this morning and there was no line. I took two more and still no line! How did I end up with a faint line yesterday? My cycles are all over the place so it's hard to know for sure when to test or how many days it's been post ovulation. Any advice or thoughts or opinions would be soooo appreciated. I'm going nuts!
