Hello, thanks for the query to H.C.M.
Still there are fatigue, nausea, frequent urination
all these symptoms are due to anxiety through which you passed for pregnancy
conditions , whether you are pregnant or not.
But still there is constipation
so for this you have to take some fiber diet with plenty of water.
Appetizer and antacid will work for you ,but please take these two at the advice of some doctor.
Still there is any dilemma than get in blood examination for Haemoglobin
is less than 11 grams % , than it is a cause of concern otherwise need not to worry and enjoy life.
