i'm 20 yrs old and sexually active and have been in a long term relationship sense i was 14. I have had the same fluttery sensations but it's not just in my abdonmen but also my sides and in my kidneys. I wish i could get it checked because i to along with many women am driveng myself nuts wondering that P word. I know condoms are not 100% safe, but i have normal periods. I pray that i am not pregnant. even though i would be a very nurturing mother and would never think about adoption or abortion I am not ready to be a mother. However this is not something i can get checked due to no health insurance....any suggestions or ideas on what the heck this could be....there not painfull just different and awkward..never felt these sensations before....they are on and off all day long
