Why?

OK ladies, if pregnancy tests all say they can detect from the same time frame....then why can we get negatives on some and positives on others?

Especially if you are using the same urine.

It just doesnt make sense to me.

Maybe someone will have the answer...LOL

Sorry chrissy I dont, but hopefully someone does as that is an excellent question.

Some are more sensitive than other and measure 10 v's 25 (and I can not remember the units that it is measured in) so you might get a BFP on a Fortel Ultra on 13 DPO for example and a BFN on a Crystal Clear etc.

Yep as Angelic said some can pick up lower levels of hcg than others. Which is why you may register on one but not or really faintly on another.

Love

hmmm, i dunno....i guess i will go on to not 'trust' certain brands as much as others.

Chrissy,
Firstly, huge congratulations for your BFP - well done!!
Which brand of HPT did you find to be the best for your + result?

Also, I have a few more questions for you about preseed. If you have time, would you mind answering them in the Conception forum under the pre-seed topic posted by Flowerchild? Sorry to be a bother but I like to talk to those who have actually used the product for tips!

Hope you have a very sticky little one with a fab pregnancy to follow!!
