Frustrated

My boyfriend and I have been trying on and off these last 3 years and I’m starting to notice that when I’m ovulating he’s not in the mood for sex at all I’ll even tell him I’m ovulating and we will still end up not doing it I understand he works and he’s hours of working are different then mine ... but still I feel like he has no interest in trying to have a baby with me anymore ... Im two years from 30 and I feel like if I don’t have a baby now I won’t ever be able too , I suffer from pcos if that doesn’t make things harder... I’m on the verge of just giving up all together
