I'm about 6 days late on my period. but my cycle isn't regular due to weaning from breastfeeding. should i test? my cervix is low, hard, and closed

Doesn't hurt to: The first morning urine is often more concentrated and can give more reliable results early in pregnancy. If there's a chance you could be, it never hurts to test. However, the urine tests can be less reliable early in pregnancy. The test relies on chemicals made by the developing embryo/stalk and it must get to a certain size before enough is made to turn the test positive.
