Lately I've been extremely tired, nauseous, I've had heartburn which I don't normally get, also my breasts are sore with blue veins showing up, and I've had an increase in cm (sorry if that's tmi) I've also had cramps but they feel more like little twinges. I only have a day left until I'm due for af so I can't tell if I should test now or just wait it out because where I live the tests are really expensive
