Hi everyone. I've had five unexplained miscarriages and am now 16.5 weeks with my sixth. I'm on clexane and aspirin this time, I've had three scans and the midwife listened in to the heartbeat last week. That should all be reassuring but not to me! I got the angelsounds doppler today and am not sure if the heartbeat I heard was mine or my baby's. I'd like my hubby to have a go later because he's far more level headed than me but there's nothing in the booklet about how many times you can use it. Is it once a day? Less?
