Is DPO after ovulation DAY or WEEK?

Question

DPO after ovulation DAY or WEEK?" /> 
This might be a stupid question but I’m just trying to understand. I’m TTC for the first time and I’ve read that you can take a pregnancy test between 8DPO-14DPO but is it after the actual ovulation day or after the entire ovulation/fertile week? Please don’t judge, as I already said this is probably a dumb question but I need to know because it’s confusing. I also don’t even know if I posted this in the right group lol.

Answer

It stands for Days Past Ovulation x
