It is common to have indigestion
and heart burn in pregnancy. So you might be feeling as not having food.
Few women experience diarrhea in pregnancy just before going to labour.
Still we need to rule out infectious origin for diarrhea- passing blood/mucus, fever,abdominal pain
. If you have you need to consult doctor
for further treatment.
Throwing phlegm is no problem if you dont have fever, cough,breathlessness.
If you get more severe symptoms, get ultrasound
done to check how your baby is doing, to be on safer side.
