28th November 2011 08:55Hey guys, Just had my first scan. I thought I was 7 weeks but the foetus is only 3.7mm and so is measuring about 5 weeks. Normally this wouldnt bother me but I did chlomid (though it didnt work and didnt have the follow up injection) and based on that I know when I ovulated which should measure at 7 weeks. But - the foetus was flashing - ie a heartbeat. Back in 10 days and hopefully he / she will have grown. This is such a nervy time.
