Never late

Hey ladies! I’m a 28 day cycle faithfully. Always have been aside from my pregnancy with my son and my chemicals. I never realized or thought anything of it because my partner and I literally did not have sex this month as he was away in the field and I’ve just been wanting a break from trying. So I know 1000 percent I’m not pregame from this past month. The only thing that got me thinking is that my breasts have gotten increasingly tender the last few days which only happens right after ovulation for me. And extreme tiredness isn’t abnormal for me after ovulation and before my period. Also depressed so the fact I’m sleeping more doesn’t surprise me. I always ovulate like clock work too. On cycle day 14-15. My body is so scheduled lol. Do you think I just ovulated late?? I know I can’t be pregnant from the previous month because I took a test the day before my period started and it was negative. Any clock work ladies have this happen and what was it? Im confident it’s nothing serious. Thanks for the help and advice ladies!!
