Help.. has this happens to anyone?

My husband and I just stared trying for our 3rd one. This has never happens to me before so I’m a little confused. I can’t really remember if my period came on the 3rd or 4rd of this month, it lasted about 8 days. I have been taking digital ovulation test (which I have never use before, I have only use the strip ones) and they have not datected a positive ovulation day up to this day. I did not test on the 19 and 20 since I was out of town and forgot to pack them. I have been having sex every othe day. I have log in every day on the app and since I haven’t have a positive ovulation test glow is giving me a later period day for November? Do you guys think I ovulated and the test didn’t work or possibly I ovulated during the days I did not test? I’m so confused and do you guys think I should start testing for posible pregnancy?!?
