All messed up

Hey Glow Family- i have to get this off my mind and I'm hoping there is someone out there who can relate-I am feeling pretty discouraged- I have been ttc for several months. I have pcos which I has been warned may make it slightly harder to get pregnant- also with the irregular periods makes it harder to judge the best "time" to ttc- I am so confused because last month I had all the sure signs I was pregnant-expect the positive test! After a few weeks of testing I figured safe to say not this month! We will try again next go- around... Next go around get a positive on the ovulation test- have intercourse- two days later start my period-or what at least seems to be - has the horrible cramping and pain like normal, the moodiness, the sleepiness and the nausea and the tiredness (at least these are normal ever period for me) but is MUCH MUCH lighter- any who two days later for a period after a positive ovulation test... I always though that ovulation was more or less "mid cycle not a day or two before you period... So now I'm feeling discouraged because ya another month where nothing is going to happen 😔
