I think I missed my chance this month :(

So according to Pink Daily and the glow app, I am supposed to ovulate today but since I was running late for work I didn't have sex with my boyfriend. Even though I had sex with my boyfriend 3 days ago, I don't think I caught the egg. My gut says I didn't but who knows? It's my 3rd month TTC my rainbow baby. I thought I got pregnant last month because I did it like the day before ovulation and every sign in the TWW pointed to pregnancy but no, AF came when she was supposed to. Do I still have a chance even if we did it 3 days before ovulation? I feel like I missed the egg this month also... If anything, there's always next month..
