Not kicking in??

I hadn’t eaten food in a very long time, and took a 25mg edible. I must’ve taken it almost 5 hours ago, and I still don’t feel anything. This is my first time trying weed. Saw some people saying you need to have fat or carbs in my stomach before, but I hadn’t eaten anything in 10-20 hours. Did I ruin this edible? Did my body digest it and not “use” the THC, I ended up eating a bit past one hour after I took it. But I still don’t really feel anything. Yes they’re legit and from a proper dispensary. — Should I wait a bit longer? Or should I eat more food and try another 25 mg (50 total now) ?
