I'm 5 days late and still no sign of periods, I don't know what to do, I've never been late on my periods & plus I had sex the other night it usually brings my periods on faster but not this time, my nipples are really sore , I don't know what to do, I don't know if I'm pregnant or not & it's starting to scare me , any advice please ? 😏😔
