I just need encouragement

I have been trying for my second for 10 months this month will be 11. I miscarried my first and then got pregnant three months later and gave birth to a beautiful boy December of 2018. Now I seem not to be ovulating regularly as I’m missing cycles and have cycles that are 40-45 days long. I really want another baby and am only 25. Idk what to do but this is making me so depressed. I love my sons to bits and would love for him to have a sibling. Please encourage ya girl in this time .
