Have been having sever pains since morning going to pee every few minutes but not coming out with much. Have been to hospital (the pain was so severe that I thought my stomach would burst). Thay have given. Me meds and sent home. Have had three doses of cephalexin but not one jot of difference. They also gave codeine bug it didn't even touch the pain. M 9 weeks and just need a bit of sympathy :(
