Ovulation

Hello ladies.... so I was wondering if you could get pregnant 🤰🏽 3 days before your ovulation date? My husband and I have been having sex for the last 3 days than missed one day than 3 days prior to that. I have not been seeing CM at all... what does that mean... does everyone get CM before ovulation? I have before but just not for the past several months. But I always have my period on time... this app says I ovulate August 3 and another app says the same thing but I do have one app that says I ovulate tomorrow August 2. Anyways can I still get pregnant? And we did not have sext today.
