Possible partial molar

Hi ladies, so long story short- 1st dr diagnosed a missed abortion at 10w where baby stopped growing at 8 weeks, I was referred to dr 2 for d&c;, dr 2 said I need an oncologist because it looked like a partial molar to him. Dr3- oncologist didn’t believe it until my hcg came back as being 412k. Huge right?! I was immediately scheduled for a d&c.; 4 days after d&c; my HCG was down to 16k! Know it’s still high and it’s a long way to <5 but I think that’s down 96%. My oncologist was thrilled. I think the minimum they look for is a 10% drop per week. (Is this true?) Pathology is still pending and my next blood test is Friday.

Has anyone else had this or have been at this level and how did you drop? Google is failing me.

Thanks!!
