Great question, I have a similar question... I tested on cd38 on Sunday and got a BFN (cycle normally 34-38 days, occasionally 40+)... No AF today on cd43 so decided to go to GP and did a First Response test before I went which looked like this... Took a photo and showed GP and she said it looked positive... But then she did two tests and both were negative... I've been for a blood test but the results aren't back for 7 days... And I'm too scared to test again.
Emma, The FRER picks up HcG at a lower level than the cheaper ones at the dh's so I would hazard a guess that it is very early days and if you did a dr's one 2 days later it would show up. I happened to see my gp the day I tested even fainter than that and they did not even bother asking to see my faint line or test witht theirs (I needed medication prescribing as soon as pregnant). I got a line on FRER on a Wed but a not pregnant on a CB Digital. The next day I got a 1-2 weeks pregnant on CB Digital. ( am 6 weeks now and get strong lines on all FRER tests etc!) Good luck!
Thank you so much RooibosTeaAgain... You were really reassuring and have saved me going mad these last 2 days. I gave in this morning and did another FRER and the line is definitely darker than it was.... Which I'm hopeful about... Tomorrow I may go all out and try a CB Digital... I'm just wondering if the HCG would have been strong enough in my blood on Friday when they took the blood to get picked up... Not sure I'll be happy until the GP gets a positive test of some sort!
Emma, it is the doubling of the level in the blood every 48-72 hours that matters and not what the number is that matters. Anything above 5 is pregnant! Most NHS dr's do not bother with blood tests as home tests are so reliable. As you can tell from your two FRER the line is getting darker. Congrats!
