18dpo - when to get a blood test?

Google83

Hello, 

I'm currently 18 dpo, temps staying up-ish, no sign of AF, and tested with a BFN lastnight. According to TCOYF, if I hit 19dpo (3 days past my longest LP) then there's supposed to be a very good chance of pregnancy - but I have also heard of lots of women starting AF much later and never getting a BFP... Or never getting AF and not getting a BFP until later in the pregnancy. So confusing :P

 At what point should I ask for a blood pregnancy test?   

Thanks!

With all those missing temps and BFN, I would question whether or not your O date is accurate.  I hope this is it for you, but I would wait it out for a bit before asking for a blood test.  Good luck!

Why not take a HPT? I question your O date as well.

ETA: I need more coffee. I see you did already. Keep testing once a week until you get a positive or your period.

And...you're bleeding.  Probably not a good sign.

That chart is aweful.  I would not ask for a blood test and next cycle I would try and be more diligent with your charting.  If no period or BFP by 60 days, then I would call your doctor.  I don't believe that you are actually 18 DPO.

Thanks for the responses ladies!  

I know there are lots of open circles... I got so discouraged after the last cycle that I only halfway charted this time, just enough to confirm O. I feel pretty confident about my O date due to the CM, CP, temp, and other symptoms I always get around that time - but it's totally possible that I'm not as far along as I thought.   

As  for the spotting, I get that every single cycle. This time it's been just a tad on four occasions, sometimes it's been much heavier once or twice, and then stops for a week until my actual AF. 

 I have my annual exam on August 1st. I may just wait until then and mention the Consistant spotting as well. 

Thanks ladies!

After you get a +HPT... but even then it's not necessary unless the doc has a reason to monitor your betas.
