I am (estimated) 6.5 weeks today. I was having some bad cramping without bleeding last week and called my doctor. She brought me in for blood work 2 days apart to monitor hormone levels. I got a call today saying that my levels rose a "little bit" but didn't double as they were expected to. I am still experiencing some nausea and breast tenderness. Has anyone else experienced this? I am worried things aren't working out like they're supposed to.
