A is the answer I've had this question before also on a health work sheet
Answer:
Hi! As far as I know, it's normal for a cycle to last 3-7 days. If you're not feeling any severe pain then it should be good. I recommend using Flo, as it helps you predict your cycles and tells you when to see a professional or not. However, since your family has a history I do recommend seeing a professional just to make sure everything is going well, even if you have no symtoms. If there is a problem it's better to find it early than to find it later it life. Hope this helps!
