Had a blood test last tuesday (9th) to confirm pregnancy which came back positive but low at 96. I think i was 4+3 then. Sent me for another test this week just to check levels are rising before referring me to midwife. Had test on Wednesday when i think i was 5+4. Got the results today. Nurse said the dr's note on my results said 'positive and rising', but she also threw in at the end 'i'd have expected it to be higher'. So i have now wrried all day long about this. I calculate that that means my levels are rising ever 2.4 days so within the 2-3. Does this all sound normal or should i be worried?
