I have been sexually active with my partner, but we have never had sex or touched each other in person..we tend to have a lot of our sexual stuff online and tease each other with underwear exchanges. This is very TMI, but I am paranoid about something. My partner gave me their underwear which had 3-day old semen on it in a zip-lock bag and I used it- i masturbated with it still in the bag. I can get bloated really bad and lately I have been paranoid wondering if I somehow got pregnant by it or not. I am not sure if what I am looking at in the mirror is me being bloated or showing signs of pregnancy. I just passed a horrible weeklong fever and have been so hungry lately and i am super scared that I am pregnant- I really need reassurance.
