I know the only way for someone to know they're truly pregnant is to pee on a stick. I use TWO forms of contraception (pill and condom) every single time I have sex without fail, so I'm aware I should be pretty safe against pregnancy, but I worry and convince myself I might be anyway. Every little thing I feel makes me think it's a symptom. Does overthinking about pregnancy cause everything I feel to me a symptom in my head? Is this a common thing for women?
