Delaying ovulation?

Lindy • Mum to a gorgeous baby boy 💙👶🏻

So my boyfriend is going to be away when I ovulate next cycle (according to glow) and he’ll be back a couple of days after. I googled delayed ovulation and there were some posts about vitamin b6 having delayed some women’s ovulation. I was just wondering if anyone has experience of this or any other ideas. AF due tomorrow and I know it’s coming, don’t want to miss a cycle as been trying for nineteen months now. Grateful for any advice!
