I could also be 8dpo. here's the story. So basically I had sex on the 21st of last month and O'D between the 23nd and 29th. But then I BD on the 18th and was supposed to O between the 20th and 28th of this month. So I still don't know when edd would be. still holding on faith to this faint positive till I can test again. any advice on how far along I could be? can you guess by the picture? let's see how good your eyes are.
