Hello, my 23 year old daughter has severe cramps the first 4 or 5 days of her period. Her period last 7-8 days. After he period is finished 3-4 days later she starts spotting a dirty blood color along with fresh blood. The last two days her tampons are having a hard time staying in, they are wet but not just with blood. she has had to urinate more that last few days as well. any thoughts??
