Hello, I'm 17 years old. My periods is kind of regular. It sometimes can be late max for a week. This time I'm late (if I can even say that because it's more like a missed period) for 29days. I'm a virgin. There was a few symptoms that reminded me that period will come like bloating, mood swings, acne but nothing happend. A few days ago I was bloated really bad it hurt so much, I couldn't even walk but later it was okay. At the moment I feel like a stabbing pain on my lower belly. Should I be worried? Is this something serious?
