I have no idea, if you wanna make your money worth it, take a blood test.

I agree with ka

Yeah definitely get a blood test. You can take a bajillion urine tests and they can all be negatives, so why not make it useful?

Unfortunately - with hpts as well as other things you get what you pay for. The more expensive the test the more sensitive it's gonns be to the level of hcg in your system. If you really want to good answer wait till the day of your missed period and test with a very sensitive test (yes the expensive ones which you can use up to 4 days before a missed period), and use your first pee of the morning to test. This should give you an accurate result (they're supposed to be like 99% if used in the morning and on the day of the missed period or later)

I took another test at birthright and it came out to be negative. The lady told me that I really should take the test with morning urine. I wonder if it came out negative because right when I went in I drank some diet mt. Dew quick so I could actually pee...Hmmm...Well.. I still havent had my period yet! And today is the 1st and it was due on the 25th and never been late and I havent been under a lot of stress or ne thing!!! I just havent been feeling good...Just crampin a lil right now..Not even much at all tho and I feel like im gonna throw up or somethin. Im still having backaches and these dang headaches. And my boyfriend just broke up with me because I told him I had to take a pregnancy test cuz I think I might be pregnant!!! I cant believe him! But he wouldnt be the dad tho....But he doesnt know that...You'd think that a 22 yr. Old wouldnt freak out like that.....But he said im not happy and blah blah blah right after I told him.....He text msged me that after I told him on cell phone. The guy who would be the dad doesnt know right now cuz he is in the hospital...He the one with the chrones disease... idk what to do
