I had a missed miscarriage in April last year I was told at dating scan at 9 weeks but did not miscarry until 15 weeks. Had some problems with cervical erosion and bleeding since then too. I have recently found out I am pregnant again (5 and half weeks now) . I have booked in for a scan at 7 weeks and would like to know if I should be able to see heartbeat at that point. I am so concerned about losing another one so I need to make sure that everything is OK this time. Can anyone offer me any advice?
