Implantation Cramps...untouched territory😂

I’ve been googling this like crazy lol but can anyone tell me what implantation cramps feel like? I’ve had lower back pain, side cramps, lower abdomen cramps....it’s not really like a painful feeling more or less uncomfortable. I believe I ovulated a little earlier than the app says. But I just want to know what did implantation cramps feel like to you ladies and did you notice them?
