Didn’t ovulate this month....

Is it possible that I missed ovulation this cycle? This has never happened to me before, I’d usually get the clear stretchy discharge that looks like when you have a cold and blow your nose... but this time I haven’t had anything at all. It’s mind bugging me because I had sex on jan 23rd and he hadn’t ejaculated yet but the condom slipped off his dick as he was stroking it out of me but the condom didn’t get deep in my vagina it just slipped off the entry of the hole like it was hanging there so it was easy to take out

Should I be worried? <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says my period is due in 2 days and I’ve been having random mild cramps every now and then for the past couple days/week
