pregnacy #2 im 7w6days I am having sharp pains on my left side my vagina lip last less then a minute. I got this with my daughter as well but only in the last two months . Does anyone know what this is . Also my boobs are so much bigger and my belly is getting harder . Did anyone start showing sooner then they did in their last pregnancy and when did you start feeling your baby move . Also has anyone had a vbac ?
