When should I test?

KG

So I went off birth control in September, so I know that my cycles are still regulating. For the most part we use condoms, but lately have gotten lazy and just use pull out. We're not trying to conceive right now but we also aren't opposed to the idea of starting our family now. I was supposed to get my period according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> yesterday. My cycles since going off the pill have been anywhere between 27-39 days (which I was expecting as my body regulates). I know <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> is just a best guess, so it could be about a week off since I'm not regular. There is a slight chance I could be pregnant, but I think its unlikely. Should I give it another week and see if this is just a long cycle or test in the next few days?

UPDATE: So I'm a week late now and still no sign of AF. I took 3 tests and all negative so no idea what's happening.
