She was 10 weeks pregnant and there was no heart beat and the doctor said she still might be pregnant!!!! Er i think if theres no heartbeat at 10 weeks the doctor would know. Hcg levels take 48 hours to come back not 3 days as well - get your facts right Miss Price. Plus if you are having a threatened miscarriage you do not play polo and do a marathan 24 hours after a termination!!!
