I posted a few weeks back wondering if I was pregnant. I have borderline personality disorder so some of the symptoms of possible pregnancy would be masked such as fatigue and mood swings. I didn't have unprotected sex, he entered me once and I know that could be all it takes but we used a condom after that. It's been 4 months since any intercourse or sexual contact with my boyfriend as I am in a different city at university. I can get very paranoid sometimes about these things. I took a pregnancy test the day my next period was due after intercourse, it was negative and my period came 4 days later. Then around 2 weeks ago (4 months after intercourse) I took another pregnancy test (clear blue advance) and it came up as "not pregnant". After I eat, my stomach becomes hard, bloated and gassy. I also watched a progamme on women who didn't even know they were pregnant and I just became more and more paranoid. I have gained a bit of weight but I'm not sure if that's the depression side of my mental illness because I do eat a lot more.
