hi, sorry i don't have an answer for you but i saw this & it sounds a bit like what i am having. i am only 28 weeks & for the past 3 days now i have been getting period like pains in my lower tummy, they are constant & some back pain off & on. without feeling my belly it feels like they are tightenings every now & again but when i put my hand there it is not tight at all. the baby is moving more than usual but they are really uncomfortable & changing position doesn't help at all. does anyone know what this is, i keep feeling like i'm about to get my period & that either blood, discharge or my waters are just going to come flowing out at any minute.
