Late ovulation

So I ovulated on cycle day 23, today is cycle day 33 still no period, the app has me starting on cycle day 37 which will be Thursday. pregnancy test was negative. I know it's still only 10dpo but I can feel the cramps coming on. I've never ovulated this late before, it's so weird. I've been trying for baby #2 for 8 months and went to a fertility appointment and found out my vit D was low and my husbands was too and also he has low morphology so he started some Theralogix conceptionXR supplements. And I'm supposed to go in on the third day of my period for an ultrasound. I was hoping to just get pregnant but so far I'm not. Anyways just venting 😊
