The longest it has ever taken for a pregnancy test to show positive

[ambertwogood]

I'm wondering what was the longest amount of days youve ever had to wait to get a positive test. From what I've ben reading you shiuld wait atleast eighteen days dpo to test and some have said possibly eighteen days post implantation if you have an idea of when it occurred. I am four days past implant if I am pregnant, I got a faint pos. On an Answer brand pt, but am not sure if its accurate, even though the line is def pink, and through and through and solid. But I took a u check one that evening and it was neg. From what I've read answer can be very sensitive and aren't prone to evaps, and ive read alot of women have got false neg with ucheck and even though they say it is 25miu several people don't believe it as it took several erjs into their preg. For the test to read pos. One women said she was five weeks before it came up, another said her beta was over 900 and it still was neg. I'm thinking that since I adm prickly only four days past imp. That it would be entirely toooooo early for a test to read correctly, and ff says if I od when I did that I should not test til the friday after next. So would like to hear the longest it ever took your positives to show after getting false negs, and if it was after af was due and how long after af?

Also, if anyone can answer what is the normal amount of hcg in the urine at implant and what are the normal ranges as each day passes, including low and high ends of hcg levels?

I don't know about ranges but a friend of mine's AF was 5 days late last May and she did a home test and it was negative. She didn't test again till she was 21 or 22 days late and then she got a BFP.

Another one was a few days late and went to her OB who did a blood test. She told her it was negative and that her AF was probably late due to other factors. At about 20 days late she did a home test and it was a BFP.

thats crazy. You shiuld find out from the doctor when they do a blood test of it is going to be quanitive or qualitative. The later only says pos our neg and a quantitative bid test will actually say what the exact level of hcg is, bc a qualitative usually won't say positive until hcg is above 25miu
