I know on the box it says to wait until you're closer to your period or at least days after your ovulation but I'm assuming that's only for if you've had sex during that ovulation period?? I had unprotected sex over a week ago and I'm on the pill. I was also on my 3rd day of my period. I'm ovulating right now and (hopefully I'm wrong) am feeling a few signs of possible but hopefully unlikely pregnancy. I bought first response but I don't want to use it if it won't give me a truthful answer
