Implantation

Has anyone had implantation that lasted more than just a few days? Going on Day 4 and it’s not much at all just every other time I wipe when going to bathroom. I’m 5 weeks 5 days. I had ultrasound 2 days ago and they could see possibly two sacs but since it was so early she wasn’t for sure. (Elective ultrasound at a clinic so it was abdominal) I did talk to my doctor and she said from what I’ve described it’s implantation
