Experience with "Tell Me Pink or Blue", especially if you've already had a boy.

I am toying with the idea of taking the "Tell me pink or blue" blood test. I read it's pretty accurate, but the only thing is bc it scans for the Y Chromosome, if you have had a boy in the past it could pick up on an old Y chromosome and then give you a *possibly* false boy result. I was just wondering everyone's experience or thoughts on this test. My situation is this, I was MCed October 2009, got pregnant the following December with a boy. I gave birth Sept. 2010 to DS1. Then I got pregnant June 2011 with a boy. Gave birth Feb. 2012 to DS2. I got pregnant this past Decemeber (2012) and i am now 11 weeks pregnant, so obviously not sure what i am having. But as you can see i have some pretty close age gaps. DS1 and DS2 are 17 months apart and DS2 and this bump will be about 18 months apart. Im just wondering if it would be a waste of money? Im afraid it will pick a boy result bc thats what i have been pregnant with both times and pretty recently. Or do you think it would actually be accurate? thoughts?

How much does it cost? How long does it take to order do and get results?
These are questions I would ask myself
I'm just waiting till 16 or 17 weeks for an u/s

I already have the answer to that. Its on their site. Thats why i want to know if it would be accurate given my boy history. I dont want to pay tons of money for something that could be inaccurate bc i have two boys already. But this is my last pregnancy, so im willing to pay a little bit of money if its something that would actually be right. but if theres a good chance it would be wrong, i wouldn't want to drop the cash for it.

I just read something on ingender about 25 people being told boy and 15 had girl :s

A lot of people seem to have accurate results too from what I'm reading... Hope someone else has some insight for you

yeah, im reading IG now too...making me rethink getting it lol.

Ya cause I thnk you will just second guess the results no matter what after reading mixed reviews

^very true.

Just wanted to update, I've decided not to waste my money on this product.

I would only trust a blood test. That materniT21 one works.
