My friend and I had sex using a condom. Today my friend's period is 4-5 days late, accompanied by abdominal pain and chest pain. Doctor, I'd like to ask if my period is 4-5 days late. Doctor, I'd like to ask if I had sex using a condom but my period is 4 days late with abdominal pain and chest pain, am I pregnant? During the past 20 days, there has been no bleeding and I've been taking medicine for stomach pain for about a week.
