13 DPO BFN Do I still have a chance?

[LindsayDawn]

AF was due on 11 DPO (I have a 10 day LP). It's 13 DPO and still getting BFN with FRER. Do I still have a chance? I'm very sure of when I ovulated - my chart is beautiful this month. Temp hasn't gone triphasic, but also hasn't dropped.

I'm losing hope, because with first miscarriage and with DS I got a BFP on 11 DPO, and with second miscarriage I got a BFP on 10 DPO.

[LindsayDawn]

Sorry. Re-phrasing my question:

Does "Accurate From First Day of Missed Period" apply to someone whose period always comes on 11DPO? Or should HPT boxes say, "Accurate From 14 DPO"?

How long your LP is does not affect when an HPT will be accurate.  It's a matter of implantation time, how much hCG the embryo is producing, and how quickly you metabolize hCG. There is a correlation between late implantation/late BFP's and early miscarriage, but I would not consider 10, 11, or 13 DPO late for a BFP.  The typical timing is 12-14 DPO for accurate results.  So, in short, yes there is hope!  If you are totally sure of your O day (can you share your chart?) and your typical LP is 10 days long (so is mine!) then going 3 days past that is an excellent sign of pregnancy.  I would pick up some dollar store tests and test every morning until you get a BFP (you can confirm with your FRER then) or AF shows up.  Keep us posted!

Thank you!

The beginning is wonky because of chemical pregnancy last cycle.  :(

Ah, well, I would not at all say that you O day is absolute!  Even FF is unsure, hence the dashed red lines.  The uncertainty lies in the fact that you have three different levels of temps: those under the CL, the first 5 temps above the CL and the next 8 temps after that.  This could be interpreted as triphasic, but implantation should occur between 6 and 12 DPO and 84% of the time occurs between 8 and 10 DPO, so it does not seem very likely to me at all that your temps would jump ON 6 DPO instead of after it.  The first set of temps above the CL are similar to your temps earlier in your cycle.  I know you said they were higher from a chemical pregnancy last cycle, but maybe they weren't and that's just your normal range of pre-O temps?  Additionally, you marked EW just 3 days into your LP, which is not common.  This is generally a very dry time.  And then you did not mark CF at all after that.  Unfortunately, it would be very helpful to know if you continued to have EW on CD 18 and 19 and if it dried up after that.  If this was the case, you may very well have O'd on CD 19.  That would only make you 8 DPO today and definitely explain your continued BFN's! 

So with this information, I would still say test again tomorrow if you'd like with a dollar store test, but that you should save that FRER for 3-4 days from now if AF has not shown up.  Keep us posted!!

Hmm. Cover line is usually 97.3 - 97.5, so I didn't doubt it.

That stinks if it's wrong. There wasn't any romance left after CD15, if you know what I mean.  ;)

When there's nothing listed there for CM, that was completely dry.

Thank you!

[Jaimee]

Well, sperm can last for 5 days or so in fertile CF, which it seemed like you might have had during that time even if it didn't make it's way all the way down.  FX that you did O on CD 14, though, and your BFP is just around the corner!   Make sure to mark dry days as actually dry, not just blank- especially around O.

[LindsayDawn]

Thanks for your help. Brown spotting now, so I guess it's my late AF, or perhaps 8dpo implantation spotting. Probably the first, but I can dream!

[Jaimee]

Maybe... as it's brown it could just be old blood finally making it down.  FX!

[LindsayDawn]

AF today. Just wanted to say you were right about that EWCM on CD17. My temps aren't right for it, but I must have O'd then = my usual 10 day LP.

[Jaimee]

Maybe, but without fertile CF, I'm not inclined to move your O day.  You may have elongated your LP a bit.  We'll have to wait and see what next cycle brings!
