We've been trying

Sarah
My partner and I have been trying and it's only been 2 months. Today he texted me and asked "does it bother me". I answered him honestly no. But I believe it bothers him. I've visited my doctor all throughout 2015 ( Fertility check ups) and I go yearly. They informed that everything is fine on my end. I just started taking prenatals in Mid January.  So him asking that I know
It bother him. During my fertility stage and ovulation. We hardly had sex so I don't think we have been trying the right way. What are you thoughts? 
I've heard to use a tampon after he ejaculates in me to kee the cum flowing. 
Check my temperature 
Purchase the ovulation kits
Eat sweet potatoes
What do you suggest? And when should I begin to worry?
