I'm 30 weeks with my first, been having what I thought were Braxto Hicks for sev weeks now. Feels like my belly gets tight and hard and shrinks round the baby, doesn't hurt, just notice it after sex or randomly, but only once or twice a week. Last few days been having this with movements (certain positions when standing up, lifting things, walking quickly)-is this Braxto Hicks or contractions? Had about 4 or 5 today, not sure if I should ring the labour ward or wait until morning.
