Pregnancy after loss

I miscarried 2 months ago at 12 weeks, after my D&C the path report confirmed Triploidy syndrome. A syndrome not compatible with life where the baby has 3 sets of chromosomes (a total of 69) I’m now pregnant again, I thought I was 7 weeks going by my last period but the scan I had yesterday showed the yolk sac about a week behind that and fetal pole not able to be seen yet. I didn’t get a PPT until 4-5 days after my missed period so I’m hoping I am in fact too early to see the heart beat. Nausea is getting me good this time, which I didn’t have at all last time so fingers crossed for my rainbow baby 🥰
