Period coming??

Shannon

So my cycle is usually like 40 days long. I’ve had little to no symptoms (on CD 31) except for nausea and this TEEENY tiny pimple which I’m not even sure is hormonal... I think it might be from shaving. My boobs aren’t even sore. Any of you guys ever have ‘missing symptoms’ but still get AF anyways? I’m panicking because I’m not sexually active so if I’m not pregnant, there’s like no other explanation.
