How early in a pregnancy do you start to feel the fluttering inside you?

I felt that same sensation very early on in all three of my pregnancies--like bubbles or fluttering. I believe it was around 7-8 weeks for each. Everyone said that it couldn't be the fetus because the fetus is too small, and that's probably true. However, it's definitely related to the pregnancy because I only felt that particular sensation when pregnant. Never before, never in between pregnancies, and never after I stopped having babies.

Most women don't feel the "fluttering" until about 4 or 5 months along. But some women who have been pregnant before can detect it a bit earlier.

I started feeling little flutters at about 3 months pregnant but now I'm 3 months 3 weeks and I feel little taps in my belly its weird even though its my 3rd baby.

when i was pregnant my doctors said that most first time moms start to notice movement at 24 weeks of pregnancy, that was almost right on for me with my first, however with my second child i noticed a lot sooner since i knew what to be feeling for, i noticed with my second around 15 to 18 weeks, which the doctor also said was not uncommon.
