Threatened miscarriage

Kay

Has anyone had a threatened miscarriage. I had bleeding and cramping over the weekend . My doctor did an exam and said it’s a threatened miscarriage. Since I’m just 5 weeks it’s too early to hear the heartbeat so I have to wait to see if the pregnancy will continue or if I will miscarry. Has this happened to anyone and they went on to have a healthy pregnancy ? Or any tips for things I should do to help preserve the pregnancy ?
