I saw 2 doctors for 3 times from 6wk to 7wk3d and they couldn't found the heart tone and the bb size was too small. They both think it's abnormal and they bb has problem (missed abortion). I did the operation yesterday and now take a rest.
When bb was 5 weeks 4 days already checked heart tone but very weak. Yesterday 7 weeks 4 days, heart bit 173 very fast and bb size is 1.6cm, also has head, hand and pat pat and size is 6.6 cm.
