PCOS....

Laura
Hey new to posting not sure of all the key words and what they mean.
 I was told I have PCOS when I was 14. I managed to loose 6 stone in past two years & was told this would improve my chances with fertility. So recently my husband and I have decided it's time as ive not got my health in check and I stopped taking the pill and actively trying to concieve our first baby. 
Took last pill beginning of October & had my usual 4 day pill period from 10th October then did not resume the pill again!
I waited almost 6 weeks had no withdrawal bleed no spotting and two failed pregnancy tests as I was sure I had symptoms and hadn't had my period! 
Then on Saturday I got bleeding..heavy and only lasted 3 days! 
Was this a withdrawal bleed six weeks on? Or was this a period? 
I am finding it hard now to predict when I will be ovulating..can I go ahead and just keep trying anyway at any time or does it have to be during ovulation window? Appreciate any feedback sorry im new to all this & finding all very hard to understand as ive been so scared for so many years about trying due to PCOS.
