I'm five week and three days pregnant through IVF. During last three days little bleeding have been observed intermittently . Initially Doctor told that it is not always due to the miscarriage .She changed the medicine and told me to wait for some days. But yesterday it bleeds a lot . I was so tensed that I started vomiting . But when I visited a Gynaecologist he scanned and told that the SAC is OK and its size is about 11m.m . Blood appeared due to some other reason. Also , the report says that featal pole and yolk sac are not visible . Also he says that heart beat comes after 6 Week . Can any body say that still I've a chance of maturity.Does anybody have the experience of appearance of heart beat at later stage . Please tell me.
