Hcg..

My hcg is dropping. It dropped by 200. I'm 7 weeks. I know there is no hope. I wish there was. I have said that if I had one more m/c that I was gonna get my tubes tied. I cannot go through this over and over. Do you think this is a silly choice? I'm 35 I have 4 children. We wanted another one. We just haven't got that rainbow.
