For the last 4-6 days I have been experiencing a fluttering in the lower left side of my abdomen (about 2 inches to the left of my bellybutton). Its becoming more noticeable due to the almost pleasurable sensation I get when it happens... It happens sporadically, but I have noticed it more when I am sitting down or reclining on my bed.

I am a healthy 20 year old woman. I currently weigh 110lbs and stand a 5'0''.

Now, I haven't put much thought into it, but pregnancy (although highly unlikely) may be possible. Here is a quick rundown.

On Nov. 4th my boyfriend and I had unprotected sex for the first time, we used the pull-out method, and I watched him finish himself off ofter he pulled out. ((I do not need a lecture on safe sex, I am well versed in sex and the like))

On Nov. 6th I started my period. It lasted until the 10th. Medium-medium light flow. Pretty much normal for me, since my cycle is regular. (I am expected to have my next period on the 4th of Dec.)

I have just finished ovulating, but the flutters are still happening, and have seemed to have gotten more frequent.

I have done some searching on the internet and came across several questions on here about something similar. I am not constipated nor do I have gas. And the fluttering is NOT painful at all - if anything it feels like I get aroused by it. Oh, also, speaking of arousal, I am very easily aroused lately. I have never been sensitive before, and now I find that when my boyfriend so much as touches my arm I end up getting aroused. (probably too much info, but it may be important)

I am not panicking about this just yet, but some advice and/or opinions on this would be helpful and appreciated. If it continues or I feel any other symptoms, a home pregnancy test will be taken, then a doctors appointment will be made.

Any ideas/opinions/input on what the flutters could be (if not pregnancy, gas, or AAA)??
