Must be emotional bout to be on my period and being cray

My son is 8 months and I thought I was pregnant ( my period has been completely weird since giving birth ) and I’m kind of sad I’m not. Is that weird? I always wanted a big family, and I just miss being pregnant in general. He was my first. Im only 23 but I’m pretty financially stable so I wouldn’t be bringing in more than I’m capable of caring for.
