miscalculated ovulation, the main question is at the end !!

So since December my glow calendar has been acting crazy. Says one thing on the <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period calendar</a> and another the bubble calendar.....so in December my period started just 1 day earlier than glow predicted and I tried to fix it but it added a whole other week and was just a mess...so I thought I fixed it since on the <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period calendar</a> it was showing me correct days but I completely forgot that since it added me a week of period MY OVULATION also moved dates. I want to get pregnant but husband isn't sure yet so if it happens he'll be happy. 
Anyway...we had unprotected sex on the days I was ovulating (how I recalculated-7days after period) not how glow was showing me and I took an OPK on the day glow was telling me I was ovulating but it was negative so I thought it was weird. I didn't think anything until now since my period symtopns were coming (cramps and sore boobs even though last month I didn't have sore boobs.) but then when I went back and calculated everything I kind of hope there is a chance. I'm 12 post ovulation, my period was supposed to start 2 days ago but I took a test today in the morning and it was negative. Should I wait more ? Or 12 days post ovulation should be enough time for the test to detect pregnancy.? (The test that I took said it could detect pregnancy 5 days before missed period )
