Hi all, I wanted to post in case anyone searches for a similar situation. I tried to use the clearblue how many weeks to see my pregnancy progressing after a molar last year which needed chemotherapy as it turned cancerous. When I used the test I expected to see a 3+ because I was 5+4 (5+2 on dates). However it came up as 2-3. I was terrified and ordered hcg bloods privately for £120!! They came back at 8,900 which is 4x the threshold to get a 3+ on the test. So basically they are rubbish and I am measuring more like 6 weeks!
