Hello Dear. If you are sure you did not have penetrating sex then the chances of getting pregnant is nullified. But in case you have any doubts you can get a urine
pregnancy test (UPT) done. UPT kits will be available in medical stores.
Since you are under
stress it could be
gastritis also which is causing your symptoms of
nausea. I will tell you few tips to overcome gastritis.
1. Do not eat spicy food
2. Take medications without fail as prescribed by your doctor
3. Take little food at frequent intervals. Breakfast around 8am, small snack at 11am, lunch at 1pm, small snack at 4pm and dinner at 8pm
4. Drink plenty of water
5. Do not take much of stress. Stress aggravates gastritis
6. Do regular exercise. Atleast half an hour per day
7. Learn
meditation techniques
8. Follow this regularly for 21 days. It is said that anything you practice regularly for 21 days becomes a habit
For
sinus infection you can take a course of antibiotics as prescribed by your doctor and steam inhalation. Put some
vicks vapor rub in hot water and inhale the steam. Gargle with salt in hot water. You should be fine by them. Follow all these things i suggested.
