i have irregular period too and it makes it so difficult. .. I heard checking you temperature every morning to find out when you ovulate helps too... @alissaa93
I'm using a calendar so I know when it's good or best to have sex. Then keeping my hips elevated for at least 15 mins after. Idk if the second part works though this is our second month of trying. So I can't say much. Also make sure you're having regular cycles. That's my problem.
I'll have to try that too @acarbone
