Ok I know pregnancy tests aren't 100% but what are the chances of low hgc levels 3 days before period due?
I tested 3 days before I was due for AF. (Friday night) AF was due monday and its now wednesday and still no AF.
I knwo they are all different and can be wrong but on an average what is the chance I am pregnant when I got a negative 3 days before AF was due.

Well I took a "Best" test yesterday after work, and it was negative, but now Im worried why AF isnt here if im not PG. I think Im goignt ot book an appointment with my doctor this weekend to see what she thinks. Thanks for all your imput. Might not be on here much longer, its kinda depressing everyone else having babies and my hubbys not even here to make em. lol All the best to the rest of you.

Some tests are made to detect the hormone early, but not all. I would suggest waiting another few days to test again. You can also go for blood tests! Good luck!

First response have been proven to catch a level as low as 12. I would retest since its been a couple days after your period was due. If still negative contact your doctor and request a blood test.

chances are 50/50, you could have very low levels that is not at 25, thats the lowest a test will pick up. If you used a first response, those are pretty acurate, and it could be that you ovulated late which would cause your AF to be late(ovulation determines the day AF will come, thats why some women AF ranges from 28-30days like mine, i dont always ovulate on CD 15, sometimes it was CD18 18 and even CD14, so my AF would come about 14 days after i ouvlated either ending in a late AF or early AF depending on when i ovulated) Hope that sorta helped
