Tickling? I am nearly 19 weeks and have been reading up on what early baby movementioned feels like since this is my first. Most people describe it as butterflies or gas bubbles but sometimes I feel like someone is running a finger *very, very* lightly back and forth like tickling and I have the urge to scratch it. It only lasts for a few seconds. I only feel it on the sides of my bump but maybe that's because I have an anterior placenta. Does this sound familiar to anyone or could it be something else?
