Hi, I'm 21 years old and am a bit concerned. I'm a person who gets her period regularly with no delay at all. Well this month my period was 10 days late, and I was worried that I might be pregnant but I just got my period today. It's bright red in colour somewhat pinkish and isn't quite heavy...it's almost light for me, and I have bad cramps mainly in my lower right abdominal area. Before I got my period I was feeling nauseous, dizzy, had headaches, and mild cramps. I know this is PMS, but I usually suffer from PMS one week before my period only. I had these symptoms for three weeks before my period even started. This is not normal for me. I always, always get my period for 6 days no more no less, but the last two periods that I had were lighter and shorter in length. This has never happened to me before. Should I be worried or is this normal? :? Any advice would be greatly appreciated. Thanks.
