Is pee and bleach a reliable pregnacy test?

No: Over the counter tests work well but blood test is most reliable.

Pure fiction: Causing a fizzing reaction by adding bleach to urine or urine to bleach is purported to be a positive pregnancy test. This is nonsence. Mixing the two releases ammonia from urine which will cause a fizz as long as urine is concentrated enough. Get a home urine pregnancy kit at drug store or walmart. Quite accurate on or just after expected date of next menstrual period. Dr's test is most reliable.
