If your on the day of your expected period when does it usually start for you?

I’m suppose to start today, today I’m cycle day 31, three days longer than my last cycle, but I have a different number cycles each month it seems like, last month I got actually happy because I had a regular 28 day cycle. Today I’m expecting my period to come, I keep telling myself there’s no way I can be pregnant cause we only was able to have sex once during the fertile window, I’d love to be pregnant but I have been trying for 10 months now, I’m at the point where I don’t know if I can handle trying anymore. So we’ve just kinda let nature do it’s thing, have sex when we feel like it. I’m hoping and praying I don’t get my period and that I can be pregnant but odds are slim to none I guess.
