i already posted a message on the 'Anyone due Jan 2004' thread but wondered if anybody else had some wise knowledge to pass on. My mw heard the heartbeat on Friday (12+2) and came back on Sat to let dh hear it but couldn't pick it up. She came back a few hours later to try again but still no luck. She wasn't concerned and is coming back at 14 weeks to try again but as a 1st timer I'm worried! I can't understand why it would be heard one day and not the next, even on two attempts, although I was told that it is normally difficult to hear at this stage. Mw (with dh's reassurances since then) said that he/she was either hiding or swimming about and that we were lucky to hear it on Friday. Would I know if there was something wrong at this stage? Or were we just unlucky yesterday?It's preying on my mind a bit and still have more than a week to wait to try again.
