Prepping for next cycle

So I want to get ready to make January my best TTC month and help in any way I can to get that BFP!

I’m thinking of getting opk again and testing my ovulation. I am also planning on getting preseed. Husband and I BD around my fertile window last month and even multiple times a day...but maybe we’ll start sooner this time. Last but not least possibly the diva cup!

I’m not good at taking my temps as the time I wake is not always consistent.

Do you think I’m overdoing it?!? What have you all tried?
