I am currently 8 weeks and for the past two days I have been having bad back pain  and pressure feeling on one side that sometimes go to the front and feels like twinges on the same side.   I haven't seen my OB yet.  Not til the 1 st.  I had two blood tests done at 4 weeks it was 133 and then two days later it was 285 with a progesterone level of 35.  Could this be a sign of ectopic?  Or would I have had felt this earlier then 8 weeks.? I don't have any bleeding or spotting. Just nervous.   And the pain and discomfort seem to get better if I walk.  Any opinions or suggestions?
