Tracking Ovulation

Hello ladies my husband and I are trying for our first child... We've been trying for 4 months. I am 31 and he is 33, I also have PCOS and VERY irregular cycle. I can go for months without menstruation. My last cycle was Feb 14-19. Any other women have this problem? I'm starting to think it's impossible for us to conceive. 😔 My husband is super excited for us to have a baby and keeps asking if I'm pregnant and I feel bad when I tell him No and he looks so disappointed. Any advice, medications anything that could help I'm all ears !!!!
