Too Early to Test??

Hi!
I posted this on the TTC board too:

Is it too early for HPT?

I am 7DPO, and my cycle is 29 days long. I am currently on Day 23 of my cycle. Here is my chart: http://www.fertilityfriend.com/home/2ef368

What are the chances of a False Negative if I tested today?

Thanks!

Part of it will depend on the sensitivity of your test, but I wouldn't. Implantation is supposed to occur 6 or 7 DPO, so if you are only now 7 DPO then there is virtually no chance for there to be enough HCG to measure on a urine test. The earliest test I have seen has said 4 days before AF is due, and even then the accuracy is much lower than waiting until closer to when you expect AF. If money is not an issue, then test whenever you like, but I would wait until closer to the end of your cycle to avoid that awful feeling of a negative HPT. And remember to check what your test says, they are not all created equal!

Is there some reason you are wanting to test so early? Have you been feeling any symptoms? Or just anxious to know what is going on? :-)

Thanks bear,
I am just overly anxious and want to know. I took the HPT today (7DPO) and it was BFN. :( I wish I could jsut wait and forget about it so I wouldn't test too early and be disappointed, or if I"m not PG, I don't want to keep getting BFNs days in a row. I am going to try to wait. :(

I know it can be so hard to wait, but at this point you really should wait a few more days. If you want, you could always save your FMU and see just how long you can hold out before testing, and challenge yourself to wait until the next day. Just a thought to help you get through. (((Hugs)))

I agree, it's way too early.

Thanks ladies,
I guess I am confused, because on the First Response tests I bought, it says that you can find out up to 6 days before your period is due. If that is the case, and I have a normal luteal phase, that would mean I could test 7DPO. Is that false advertising? Seems so to me!

If you read the fine print it will give you percentages of women who get a + 6 days early, 5 days early, so on.

Susan is right, you need to read the fine print. There are lots of variables that go into it. Testing 6 days early is based on a 14 day luteal phase, which would put it at 8dpo, regardless of how long your particular luteal phase is. They also say "as soon as" which leaves them quite a bit of wiggle room. Like Susan said, it really depends on when conception and implantation happened, since what they are measuring is the hcg which is only produced after implantation. If the egg is only fertilized at the end of its life, then that would put you back another couple of days to 10dpo or even later if it is slower to implant as well, but if it is fertilized right off the bat and implants earlier than most and grows quickly, then the hcg is much higher even just two or three days sooner. Does that make sense? I know what I am trying to say, just not sure it is coming out very clear! Lol! These newer tests are incredibly sensitive, but the baby still needs time to grow. I think they measure as little as 15hcg, (most are 25 now, the poorer ones are 50) but starting at virtually nothing and doubling every 2 to 3 days, it can still take a bit of time to get up that high. I do hope you get a bfp soon, so do keep us posted on how you are doing. :-)
