How can I tell “morning sickness” apart from the stomach flu or food poisoning?
If your vomiting is accompanied by any of the symptoms listed above and you have recently had sex, it may be morning sickness. If the vomiting is accompanied by cold like symptoms, high fever or aching muscles it is probably the flu. If the vomiting comes on quickly and is very violent (as if the body is trying to get rid of something in your stomach), and if it is gone within 48 hours, it may be food poisoning or a “24 hour flu.” Morning sickness stays with you for weeks on end where the flu and food poisoning do not. If you feel significantly better after vomiting and if you vomit often with little warning it may be morning sickness. The best way to tell is to take an at home pregnancy test as soon as you think you have any symptom of pregnancy, including vomiting.
