Hallow Dear, The first cardinal symptom of pregnancy is missing a period, which you have not. All other symptoms; i.e. nausea & vomiting, frequent urination and breast changes like engorgement and tenderness, dark discolouration of nipples & areola with areolar widening, tubercles under areola and secretions from nipples start about 10-15 days after missing a period. So these symptoms you are having are not related to pregnancy; they could be due to gastric upset or acidity which you can manage by proton pump inhibitor antacids like Pantoprazole and/or Gelucil. You had your menses just 27 days ago. So you are yet to miss your period. Wait for your period. If you miss it, 8-10 days after that go for pregnancy test on overnight first morning urine sample. Earlier, these tests may give false negative results. Alternatively, you may opt for Beta hCG test which is very sensitive and can give reliable results even few days before missing a period. If your nausea can let you have Proteinex like drinks, you may start from any day, whether pregnancy or no pregnancy. High protein drinks are always good for health. I hope this helps you.
