Can you get a period before implantation?

Alexandra

I had a D&E on 10/5 it’s been 6 weeks and I haven’t had a period, but I did ovulate 3 days ago with my hCG levels at 46.5 and now I’m in the 2WW. But my fear is that my hCG levels will reach 0 and trigger a period before the fertilized egg can implant in a week or so. Is that possible? Or are there other hormones to “tell my period” not to start? Just really want to conceive again & my mind is going wild that I haven’t had a period in so long that my body might trigger it the second my hCG levels are negative.
