I am battling to fall pregnant and stay pregnant. In the past 2 years I have had 2 etopic pregnancies and just last month I had a miscarriage. Please can you give me some advise on how to avoid a miscarriage. Is there anything I can take to strengthen my womb?

Did your doctor suggest that you not get pregnant so soon after each one?
This is a subject that really is best addressed by your doctor, who knows your whole history and health, and who should be taking the time to talk in depth. If not, find another one.
