I'm currently 14dp5dt and the Clear Blue test is still saying 1-2 weeks. I've still got a strong line on First Response which is getting slightly darker each day.
The threshold for 2-3 weeks is >153 mIU/ml. I really thought I'd have got to that already by now. So worried about a chemical or ectopic pregnancy. My clinic doesn't do blood tests to check HCG levels.
