Early symptoms after miscarriage

Lauren

I had a miscarriage about a month ago and me and hubby haven’t really been trying again yet but for the last couple of days I’ve felt EXTREMELY tired and I’ve been eating non stop. I haven’t had a period since the miscarriage and I’m not sure if I’ve ovulated or not. I was having some mild cramps like I was ovulating but I didn’t take an opk so I’m not sure. Is it possible to already have pregnancy symptoms or am I just being crazy??
