Devastated

Nicole
Hcg yesterday at 5 weeks 6 days (22dp5dt) was 20850. First us today and only gestational sac. Terrified as had a Blighted in 2010 but with very low betas (not checked till after us but was in 400's and didn't double). Betas this time were
9dp5dt: 242
13dp5dt: 930
15dp5dt: 2118
22dp5dt: 20850
Any chance? Just had second trimester miscarriage in October at 17 weeks. Embryos genetically tested and were "normal"
