LMP was May 28, 2012. Ovulation as per OPTs around June 14, 2012. + UPG test July 4, 2012. 1st hcg July 11- 4404, 2nd July 13 (40hrs)- 5196, 3rd July 16 (72hrs) -6182. US July 11- gest sac in uterus. US July 19- fetal HR 96, measuring at 6 weeks (by LMP should be 7w+3d). In light of the slow rising hcg, my questions are: 1) What are the chances of this pregnancy being viable at the end of first trimester or what are the chances of miscarriage; 2) Does this imply that something is wrong with the fetus development?

Thanks
