Colds and BBT/Ovulation

Torie
I have honestly been sick for about 2 weeks...
I'm on cycle day 23 and I've had erratic temps due to sickness. 
It shows I've ovulated on cycle day 19, but I am unsure if that's accurate.
Is it possible I've ovulated later due to sickness? 
Also - I had a miscarriage last month which may also play a role
