Frustrated

My husband and I have been TTC for 8 months now. We have 4 year old twins that we conceived naturally within 6 weeks of trying. I was recently diagnosed with PCOS about 5 months ago. My cycles have been 41 days apart for months and months now. So this month I decided to start ovulation testing to see when my body is ovulating or if it isn't at all. I was also dilligently using this app, everthing seemed right in line. I was about 25 days into my cycle when I started getting a high positive on my ovulation tests. It tested high for 4 days and the 4th day I started to bleed, just a little. So I got hopeful that it might be just a little spotting or implantation bleeding but it got heavier as the day went on. This morning it is like my full blown AF! I'm so frustrated and confused. Was I ovulating and starting my cylce? My chances for TTC are seeming even slimmer now! :(
