Hello,
You are having bad headache and also
stomach discomfort. You had unprotected sex with your partner yesterday and he came inside you. You are worried that you may get pregnant. You are suggested to keep yourself well hydrated, take fluids and water. Sometimes,
dehydration may cause headaches.
Headaches also occur due to low blood pressure and
hypoglycemia. Take some nutritious food and relax. Since you had unprotected sex you can take emergency
contraceptive pills, within 72 hours of penetrative unprotected sex to prevent
pregnancy. Do not get stressed up, anxiety will only cause you to get more sick.
If you are not prepared for a baby then you can talk to your Bf and get clinically examined by a gynecologist so that few tests and investigations can be done & you will be managed/treated. Stay away from addictions if any as it will cause you to get more anxious and may trigger panic attacks. Take some antacids to feel better.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
