Talk to Gynecologist on Pregnancy

Hello . I am pregnant. According to lmp I am 10 weeks pregnant but as I ovulated late so I am 7 week pregnant. Last week when I visited Dr she said after tvs that baby is 6 weeks 3days and haven't heartbeat. This week when I visited Dr she said after tvs that baby is still 6 weeks and haven't heartbeat. She recommended me to go for d&c but I don't want to lose my baby. I had 3-4 times spotting but It was just one or two drops of brownish discharge type blood. I am not feeling anything like miscarriage.plz do help me to make decision.
