Nervous

Last month I had a weird cycle. I was 2 days late. Since then I've had sex with 2 different guys. The first was during my fertile window (per <a href="https://play.google.com/store/apps/details?id=com.glow.android">fertility apps</a> which could be wrong) but he pulled out both times. The second was 3 days after I think I ovulated (according to BBT which could also be wrong as I started mid cycle &I am using a regular thermometer) he cam inside of me. Well my period was supposed to come yesterday, or tomorrow but I have no signs at all. I'm now wondering what the chances of pregnancy are?
