Hi everyone. I’m still kinda new to this. If I had sex twice on the day before my most fertile day and then I ovulated two days after. So it’s now been 4 days since we tried. There’s 12 days until AF is expected. Should I wait until the day I’m supposed to get it to test or can I do it 8 days PO. The day we did it was 27 percent & the next day was 33 percent(we didn’t do it the second day).
