Period was due Friday

Ok so the very first time I ever got pregnant was this past year in March I had implantation bleeding two days before my missed period then on the day my period was due I was pregnant ok so I know every pregnancy is different I had a miscarriage after that but since my miscarriage once i had a good period last month we started really trying again and I’ve never in my life spotted when I ovulated this time I did and so far I’m one day missed period so is it normal to not have the implantation bleeding and still possibly be pregnant? That’s my question?
