3 months PP

I’m three months postpartum my baby is the absolute best she sleeps through the night she eats so good and really just the best baby. But I want another one. I didn’t have an easy pregnancy. I found out i had hyperthyroidism and graves disease and at the time I was living with my SO’s mother and his family. It was a very stressful chaotic situation. So I really didn’t get to enjoy my pregnancy the way I wanted to. But now we’re in our own home and everything’s getting so much better I want that second chance to really enjoy my pregnancy I want to give my daughter a sibling close in age something I never thought I’d want. Definitely not two under two. But I know if I get my period this month im gonna be sad. Any thoughts or advice???
