Could puking be a response to conception if I threw up three times for no apparent reason 12 hours before positive ovulation test and had intercourse the day before?

Vomiting is not a reliable or common symptom of early pregnancy, and it is unlikely to be a response to conception. Nausea and vomiting are more commonly associated with pregnancy and typically begin several weeks after conception, not immediately before ovulation. There are many different reasons why someone might vomit, including illness, food poisoning, or other factors unrelated to pregnancy. It's always a good idea to consult a doctor or healthcare provider if you have concerns about your health or if you're experiencing any unusual symptoms.
