thanks for your query.
is not the only symptom of a viable pregnancy
, as many women do not have it at all thoughout the length of the normal pregnancies.
You should take adequate rest, prenatal vitamins
, avoid stress/exertion/sex for the time being.
Have an examination and check up with an obstetrician within a week, and take all the drugs that are prescribed for your condition.
Do not start any medication without medical guidance.
