Hi, I'm between 6-7 weeks pregnant. Started spotting about 1 week ago then bleeding a bit more heavier the last 3 days. I have bad cramps and back pains. My abdominal pain is a lot I can't handle sometimes. I went doctors and had a scan and the baby has a heart beat but the heart beat is below average at 95. Doctors have advised to take it easy. But my job is stressful and requires a lot of heavy lifting everyday. Is this going to cause me to miscarriage ? Or effect the babies stress levels? Th
