Re: How early can you take PG test?
they make the kind you can take up to 4 days before you missed period. but it is only like 65% accurate then, and gradually gets up to 99% on the day of your missed period. i took that one 4 days before my period was due, and it was negative, but when i was a day late, same test came back positive. so i guess it depends on how high your levels are at that early stage.
i think since you were on the patch, that you are probably ok, unless you forgot to put in on at the right time, etc.
just try to relax, stress or worring that you may be pregnant can cause you to be late.
good luck and take care
