Help?

So what do you think? We're thinking about trying to bd atleast every two nights for the rest of the month. Any suggestions? Also they might all be like this because I had my normal 5 day period then three days later I had a 3-4 day period. He doesn't want to get ovulation kits because it makes him feel like it's a science project instead of making love to make a new life. I can't argue with that because its to sweet so is there any suggestions anyone could give me?
