Hormonal AF

I’m feeling really hormonal I just stopped breastfeeding (which I really miss) and I have been super pissed off but right now I’m feeling like shit I want to cry about anything (like the ceasing of breastfeeding) and i have had random cramping could it be my period or could it just be hormones I also haven’t had my period in 598 days (so since before I got pregnant) please tell me I’m not crazy!
