Hello dear,
I understand your concern.
There are various causes for
miscarriage like genetic anamolies,
hormonal abnormalities like thyroid abnormalities,
progesterone insufficiency,uterine anamolies,infections,
diabetes,anaemia etc.
All the above causes should be ruled out by necessary investigations like
ultrasound,thyroid profile,HB etc.
Nothing to worry.Once the cause is treated miscarriage wont repeat.
Drinking once might not cause any problem.But avoiding drinking is good because alcohol might lead to growth retardation of fetus and other complications.
Even vegetarian foods are rich in protein like dry fruits,pulses etc.
Take healthy nutritional diet like green leafy veggies,fruits and fruit juices.
Take adequate fluids upto 3 litres per day.
Avoid physical strain and intercourse.
Intercourse is best avoided in first 12 months.
Hope this helps.
Best regards...Dr.Srilatha
