If you haven't read it - I've shared all about how my initial beta levels didn't double yet I was still carrying twins here., Hcg levels over 77,000 at 6 weeks 4 days.... a. adubou08. Posted 03-12-10. As anyone ever gotten numbers like these? They seem high to me., The only difference is that the base level for a twin pregnancy will likely be much higher. This means that in the first four to six weeks after implantation, you can expect hCG to double every two days. Until week 6 of pregnancy, doubling time may slow down to every three to four days.
