Full wean is what it could mean

I only nurse my baby boy once a day now. He is 20 months old and that one short nursing session (usually 20 or 30 minutes max) means the world to him. He gets so adorably excited as the time approaches. He runs to his room happily giggling. It's a beautiful and wonderful thing to have with my baby. When people ask me why I won't fully wean him yet this is what comes to mind. I worry that I will fully wean him before we are ready and will still have the same issues getting pregnant. Then I would have rushed my baby out of our special time for nothing! I will wonder if I could have gotten pregnant just fine on my own. I'll wonder if it was worth it. This is the reason that I have decided under no circumstances outside of his willing it will I fully wean my son before he turns 2. I hate the waiting and worrying each month. I continue to have a short luteal phase and late ovulation which worries me. I ovulated on day 21 this month but I also didn't take any vitamins or supplements. To be honest I needed a break after putting so much hope and effort into my last cycle. I'm glad I took it but I will be back on them all for the next cycle. It's 5DPO and I am spotting and cramping badly for me. I need to get my health in line. Drink more water and sleep better. It may just be that my 20 month old isn't ready. I just pray to the heavens that I can have another child! Please god! Please! I know it's only been 5 months but please at least let me have a healthy cycle so that I can stop worrying about my body. Please give me my dream of giving my son a sibling and carrying another healthy pregnancy to term. My heart is so broken right now wondering and we are too broke to go for testing just yet. So for now it's gonna be prayers! Please please please god! Please! And whe you are at it let my sister get pregnant too! Thank you.
