Boobs were sore for a few days but that’s going, I’m never late, negative test, no sign of my period. Could I be pregnant even though test are negative? I’ve not changed anything in my life style or been stressed? Period is always on time on the dot day 28 every month. I’ve had two kids already. What should I do if it doesn’t show up this month? Only time I’ve ever been late is when I’ve been pregnant. Help ladies!
