I think my husband is too anxious to conceive!

It’s been over a month since we started ttc. I got my nexplanon removed about a month ago. And immediately started trying. Every time i tell him, “I’m not hungry” or “my stomach is upset”. He runs out to the store and comes home with a bag full of test. Lol I think it pretty hilarious and cute. But! Now it’s starting to drive me crazy, it’s literally been a month! I’ve been with him for 4 years, 9 years of friendship and I have 2 children outside the relationship. So I understand his urge to want a child of his own. I think it’s a lil nerve wrecking. It’s to the point where he’s talking to the invisible baby inside of me! Lol what should I do? I don’t want to hurt his feelings, but i also want him to understand that these things take time.
