Based on the facts that you have posted it appears that your wife has undergone IVF treatment and two embryos were transferred. The beta Chat Doctor test done after 10 days have unfortunately turned out to be negative indicating failure of IVF. There are 40-50 % chances of failure of IVF and no one can explain the reasons for failure. One has to accept the reality with the hope for +ve results in next IVF cycle. Chat Doctor.  </s>
