Hello I Am Going Through Ivf. I Was 39 When

Hello I am going through ivf. I was 39 when I started. I had a tubal when I was younger. One doctor at the clinic told me my doctor was over medicated me. Then I payed for blastocyst and it wasn't done. I went in on October 20 and 2 embryo was transferred. On November 2 my Hcg was negative. I have paid out of pocket and the doctor office treats me really bad. I have one embryo left I am so scared and confused. Please help me
