I'm 6 weeks. Since before I even found out (at around 4 weeks) I've been crampy every single day, sometimes off & on all day. It's never painful (besides the few painful stabs I feel), and there has been no blood! It's just uncomfortable. Sometimes it's like mild period cramps, sometimes gassy cramps, and other times it's been like a stretching/pulling feeling. Is this normal? I drink tons of water, is there any other way to make them less?
