Confused

The last time I had my period was for five days in May and it ended on the 29th. I’ve been on the depo shot for a year and my last one was in November and quit after that which my follow up was in March to April. Around that that I had a two month period that was heavy. The first week of june I had unprotected sex on time and used the pull out method then another day I had sex with condoms and also made sure he pulled out even while using them. My period was suppose to come this past Saturday or Sunday according to this app and nothing has happened, no bleed or spotting. I have no way of getting a pregnancy test so I don’t know what to do. My boyfriend totally thinks it’s my body going back to normal and swears he didn’t come in me at all which I believe because I made sure he pulled out before and I partially believed it’s my body going back to normal but the other part is saying it isn’t that. Is this normal or should I sorta be worried?
