Mine is low too. I noticed this after I started having kids. Then I found out it was due to the hormonal balance for the first year after giving birth. Your body is signaling that it doesn't want to get pregnant again. I also have a problem while on birth control pills. They cause the same reaction for me. The only time mine is high is when we are trying to get pregnant and during the pregnancy. I am going in next month and I think I am going to see if there is something different I can try. I need to do something since my DH is only home on the weekends and is usually looking for some lovin'!
