How often should you dtd

[Choc29]

Hi. Just wondering how often to dtd in order to get pregnant. Is a few times before ovulation enough. My husband didn't want to dtd tonight and we had a day off yesterday and I'm worrying that we're not doing it enough. I'm on CD11.

I think everyone will have different opinions on this I tried to make sure we did it daily for a few days leading up to ovulation and the day after a positive opk . But the month I fell pregnant we only did it once on the day I got a positive opk , had tried for two years ...it's a lottery
