If you test after your miscarriage, you might become confused because of the false positive pregnancy test result. On average, it takes approximately 19 days for the hCG levels in your urine to disappear after you miscarry. Please note that this is just an average length of time.
RE: How long can it take to get a positive pregnancy test? I am ttc and am 3 days late but still getting negative home pregnancy tests. I have tested with dollar general, answer, and EPT.hen i was trying to get pregnant with my daughter i did 4 pregnancy tests and they were all negative. i threw the last negative one in the bin and decided that i just wasnt pregnant, about 12 hours later i got the urge to check the test and it was positive, it took so long to go positive because i was 4 weeks pregnant.
