Hi i am a 26 yr old mom of two girls and I had my tubes tied in 2007. I have been having irregular periods for the past two months (it usually lasts 5 days last month it only lasted two). I have been having alot of lower back pain, cramps, and nausea especially in the morning. I don't know if i could be pregnant or if this is something else. I also have a discharge that just started this month, if anyone can help me then PLEASE HELP!!!
