Does implantation occur on the same dpo day each pregnancy?

If I implanted on 6dpo, will I always implant at 6dpo? Just wondering since I had a big temp shift from 6dpo and 7dpo last month when I fell pregnant (early miscarriage at 5 weeks). I’m 7dpo and have not seen as drastic of a temp shift. So wondering if I’m out this month
