My period was always late for 3-4 days, and this time too

My period was always late for 3-4 days, and this time too. And on 4/2/2015, I kinda worried why the period is not normal, then I did the 3rd pregnancy  test in 15 days. And it showed positive! I didn't believe it too much but I was excited at the same time. Then my hubby went to Walmart and grabbed 10 PTs back, and I checked it again, it showed the same thing! Haha, until now I can't believe it. Thanks Glow!
