I haven't had a period in two months and I'm TTC 😔

I've been trying to concieve over a year now. I have PCOS and irregular periods. Recently I've been getting more wet down there but it's not like discharge or anything. It's not stretchy or anything just wet. I have no idea when my period comes or when I ovulate because sometimes when I thinking I'm ovulating and baby dance , I end up not being pregnant. I had brownish discharge last week which I thought was ovulation but I don't think it was because we BD again and still nothing. I don't know what else to do. I've tried going on birth control for 3 months and had a regular period for two months then it stopped being regular again. I don't want to go on BC again. Does anyone have any tips? I'm getting desperate.
