Is She Pregnate? Or Is It Stress?

Hi, my name is johnathan. After my girl friend christina had her period her and I had sex once. But we used 2 condoms. That was within the last 13 days. She in the past 2 days have been feeling tightness in her stomach, to the point where her legs were shaking. She also has been losing alot of weight. But she has been under more stress than she ever has in the past week from my moving, and our breaking up and getting back together all in one day, and she is under so much stress. So I was wondering since we always double up comdoms when we have sex, and the last time we had sex was after her last period, so its only happened once since her last period, and she also talked to a doctor over the phone and and she described exactly where the pain was and the doc said that it was coming from her ovary, could it be possible all this is happening from stress? Or is she pregnate? Also something to add, she throws up alot, and I think that that is where her tight stomach pains are coming from. Can someone please help me?


Also, I looked up stress and anxiety symptoms, and it said that one of them is tight stomach pains....While the past week has been the most stressful week she has ever endured.

And one more thing... She has had this tight stomach pain in her stomach before she started having sex. My friend said that she had the same thing, and she found out it was a cyst. And she has felt the pain before.
