The most common symptoms of gastritis include: (13) 1  burning sensations in or above the stomach/abdomen, especially around the time of eating. 2  stomachaches or pains. 3  nausea or vomiting. 4  stomach bloating. 5  loss of appetite, feeling very full quickly and possibly experiencing changes in weight. 6  hiccups and burping.
This is NOT true. If you use birth control pills while you are pregnant, the pill will not cause a miscarriage or termination. The hormones in the pill work to prevent pregnancy by stopping ovulation or by causing the thickening of your cervical mucus. So they have no affect on a developing baby.
So, even if you are taking birth control pills and decide to take a pregnancy test there is nothing that should affect the outcome of the test other than the fact of whether you are pregnant or not. Women also worry that other things like stress, alcohol, drugs, and the like might affect the outcome of a pregnancy test.
