This is going to sound really odd but...under my boobs i have these odd lines. They def arent stretchmarks (had these with ds!!) I am only 13 weeks and have only gone up a cup size. I was measured 2 weeks ago so i know im not wearing wrong size. They look abit like crease lines. It just reminds me of fat. I saw them when i got up this morning (not slept in bra) Any body else got these or am i a freak/? They go more vertically, not running underneath boobs. I am in underwired bra but always have been even throu ds pregnancy, what could this be??
