The phenomenon of vomiting and hiccups is not closely related to pregnancy, although it is said that pregnancy vomiting can occur after pregnancy, but it is not possible to diagnose pregnancy by virtue of these symptoms. If you usually have regular periods, have sex without contraception, and have these symptoms after your period has expired, it is a sign that you may be pregnant. At this time, you can buy an early pregnancy test and use the morning urine to check if there are two obvious red lines, then you can consider pregnancy. You can also see your doctor for a blood chorionic gonadotropin test to know more accurately if you are pregnant. The urge to vomit and hiccups may also be a sign of poor digestion, such as gastritis or gastric ulcer, so it is not possible to determine whether you are pregnant.
