I just wanna make my husband happy

I have an irregular period so I can never tell when I'm ovulating, I'm looking for a supplement that's gonna regulate it and give me my miracle baby. Please ladies I've been TTC for over a year now and still haven't found something that's worked for me, I just wanna give my husband the child he's been asking for and seeing all these people around me get pregnant so easily hurts. Comment what supplements you've tried that worked for you and how long you had to take them. Also any Advice on what to do to increase my chances of pregnancy will be perfect!!
