I had very heavy periods every 28 days before my miscarriage,

I had blood test results last Friday and they have gone under 5 now so I’m assuming that means I’m. I longer showing pregnant from the miscarriage ??

I’m waiting for my period but when I thought it was coming it’s literally only spotting and sometimes I go to the toilet and there’s nothing there at all, I’m really wanting to try again but I need this period to come so I know my body is hopefully back to normal, from what I’m reading people seem to think it could be implantation but I don’t see how due to the fact I’ve done a pregnancy test the other day that was negative and my hcg levels are back to normal again, please can anyone share some experience on this maybe? I’m on cycle day 36 going off the date I had my miscarriage on the 12th December?
