Nausea and a soft cervix are one of the probable, but not certain, signs of pregnancy. Ovarian cysts and short menstrual periods are not related to pregnancy, if there is no hormonal imbalance.
It cannot be determined whether you are pregnant or not, based on the data you provided.
The nausea and “getting sick every time I eat something” as you reported might be related to chronic gastritis.
Chronic gastritis is a chronic inflammation of the inner lining of the stomach. Several factors might affect this condition, but the most important is the secretion of the gastric acid. Factors that cause increased production of gastric acid include: smoking, coffee, and emotional stress.
Infection with the bacteria Helicobacter pylori might also cause chronic gastritis. The mucosa of the stomach is more damaged when it is more exposed to the effects of the gastric acid. This happens when you regularly skip meals (breakfast, for example).
You might want to visit your family doctor for a physical examination and laboratory tests for Helicobacter pylori infection. If gastritis is detected, then the doctor might recommend taking antacids or a combination of medications if Helicobacter pylori infection is found.
As for the pregnancy, you might want to visit your gynecologist for a physical examination, laboratory tests, and an ultrasound scan.
