Hi welcome to Health care magic forum. Only the abscence of period or scanty period wont confirm the pregnancy
. the other causes could be anaemia
, tension, etc. The vomiting
could be due to indigestion
, and one vomiting wont confirm the pregnancy.
Now only things which can confirm the pregnancy are urine pregnancy test, blood human chorionic gonadotropin
test, and trans veginal ultra sound
To be sure of having suffecient blood (no anaemia)in the body i suggest you some diet recommendations as take more of green leafy vegetables, pulses, sprouts , fruits, juices, egg, meat, and sea foods which provide suffecient iron, proteins
, vitamins necessory for build blood and general health.
I wish everything will be fine, and thanks for calling.
