Feeling discouraged

Hey ladies. On my 5th month ttc after a mc in February. I have pcos so I am constantly worrying about ovulation etc but have been ovulating regularly which is good. In the past month 3 girls I work with and 1 friend has gotten pregnant and I can't help but cry in jealousy. Dh thinks I'm being rediculous  and our time will come again but I am just feeling so down. Started af 3 days early yesterday. Need some healing hope and encouragement! Baby dust to all.
