No PMS symptoms yet???

Period is due in 4 days and by now I should definitely be having my usual PMS symptoms of acne and sore boobs but nothing!

I've been peeing more frequently lately and my areoles seem to be darker(could be imagining tho)

Has anyone else had similar experience with no pms symptoms and turned out to be pregnant??

I've also come down with a fever but that's probably bc I work in childcare .
