Getting Pregnant on CD9?

So my friend told me that many of the ladies she has spoken with have sworn that they conceived on CD9...so they didn’t pay attention to ovulation as much as how many days after their last period day. Anyone here had that happen? After she told me this, I went back and looked and we BD on CD9!! 😱 So, if I end up preggers this cycle, I’ll have to come back here and let y’all know lol! 🤷🏼‍♀️
