Miscarriage

Many things can be responsible for having a miscarriage like; 

• Lifestyle such smoking and drinking
• The woman's age 
• Uncontrolled diabetes 
• Incompetent cervix 
• Uterine abnormalities 
• Infection
• Certain medication capable of resulting to a miscarriage 
• Improper implantation of fertilized egg to the uterine wall, etc

Although it is advised that the woman is prepared mentally before trying to make a baby, but you can always try as soon as possible. Ensure that you speak with your doctor about your decision and for their opinion. 

Technically, getting pregnant a month after a miscarriage is a good thing; but you should however register for antenatal as soon as possible so that your health care provider can monitor you closely.  

I hope this helps?
