I had an abdominal ultrasound scan yesterday which showed the baby measured ok but the tech could not make out the heartbeat. She suggested I go back in a week as the baby maybe too small at the moment. Afterwards I had light, dark coloured bleeding and mild lower back pain. It is more discomfort than anything. I saw a doctor, who examined the blood and said it was old blood. It wasn't fresh like a period but I am still worried, especially after the inconclusive scan. The bleeding and backache are still here today. I am anxious because it has taken us over 2 years to get pregnant. I am 36 and desperate to have another baby.
