BPF + BFP (10 DPO)

[MummyMoments132]

I took a First Response test this morning as I am now 10 DPO, and to my surprise it came back with a very faint line! I was completely shocked as I haven’t been experiencing any side effects at all. I did a second Clear Blue (blue line) test which appears to have come back negative.

Has anyone had this before? Could it maybe just be too early for the Clearblue to detect hcg? I have ordered some digital Clearblue tests to use in the morning.

Pics attached for reference. Thank you!

@MummyMoments132 I can see the vfl on the FRER, so tentative congratulations! I believe those CB ultra early are less sensitive than FRER so that's probably why you see the line on one and not the other. CB Ultra Early are 10miul and FRER are 5-6miul.

Edit to add: I had a vfl on FRER at 9/10dpo and same day tested 'not pregnant' on the CB Digital ultra early with the red tip. Next day I got positive on the early digital and on same test you used here.

FRERs are normally more reliable than clearblue. However, I’ve seen a few posts recently where people have had lines then not been pregnant. There was even a thread earlier today where someone had a line on a FRER but a negative blood test.

Personally I’d wait 48 hours then use a digital. You could do it sooner but unless you can afford to buy a few I’d wait a bit.

Ah I see, thank you! Also that is reassuring. Fingers crossed tomorrow’s First Response is a bit darker, and a digital Clearblue may also be positive then? I have read the Clearblue digital tests are more sensitive that the blue dye ones (although I’m not sure if this is correct)

Check the sensitivity of each test. Most are 10miu (including some digital ones). FRERs are normally lower. But as I said, there seems to be people recently showing lines but not being pregnant which is concerning.

@Guant I saw that post too and was very surprised that those were not true lines. Hcg lingers in urine long after it drops in blood - I remember with my mc that I was testing positive for a while after. I wondered whether that poster had indeed been pregnant but it had not stuck.

But urine tests and blood tests measure the same thing. HCG. If a urine test can pick up HCG I can’t see why a blood test wouldn’t. Because normally a blood test will pick up where a urine test cannot. There’s been a similar couple of threads recently as well where FRERs are showing faint lines but no other tests are even days later. I myself have had a really obvious indent with a FRER but it was obviously grey rather than pink but it annoys me as it could still get someone’s hopes up. I’ve attached a picture of mine. (Takes a while to be approved and show up) This came up and I had a blood test 2 hours later which was negative. I had IVF so definitely hadn’t been and was not pregnant at all.

Just an update for anyone following - positive tests this morning using FRER and Clearblue digital. The FRER also looks darker than yesterday morning’s!

@MummyMoments132 Congratulations ❤️

Thank you 🥰 still can’t quite believe it as I have had zero symptoms!
