Welcome to HCM.
First of all,if you have missed period or amenorrhoea for several wk,then do a urine test for hcg.
Check result and do a USG lower abdomen for confirmation of pregnancy
or other underlying pathology.
In early wk, pregnancy symptoms basically are nausea, vomiting
, bloating, breast discomfort, headache, tiredness
So consult with your gynecologist and take healthy diet,proper rest with folic acid
& vitamin supplements. Also avoid stress and do light exercise.
Be well and tc.
