(17) Pregnancy Scare

Im honestly so stressed right now. My girlfriend and I have recently began taking our relationship to a new (about a month ago) and I’ve always worn protection during that time, and not once has one slipped off or broken. One day my gf calls me and says she thinks shes pregnant. I try to stay calm as I ask her if shes having any symptoms but she just says she’s basing this off of her gaining 6 pounds within the month. She claims her diet has been the same as throughout the time i knew her. I told her she was just growing but her constant tales of pregnancy eventually got me extremely stressed. She seems to have no other symptoms though, and shes super against getting a test. PLEASE SOMEONE TELL ME SHE ISNT PREGNANT, SHE KEEPS SAYING SHE BELEIVES SHE IS BUT ISNT SHOWING ANY OTHER SUMPTUOUS. I actually can’t do this. I regret everything.
