Bleeding during 14 weeks of pregnancy

Yes I did. Once was alot of blood. But I got no pain. I was so scared. I went to see the gynae. They did a scan n baby is fine. They gave me a progesterone shot. Then one week later I had it again. But little. I went to see the gynae again. They say its common. But can't pin point the problem. They say maybe it's low placenta. Or low hormone. As long as no pain with the bleeding you shld be fine. But please go to the gynae if u bleed to check if baby is OK.
