So I’m not really sure how effective it is but I had unprotected sex on may 1st, may 2nd both days I was supposedly ovulating but I took a plan b on may 3rd in the afternoon. Silly me proceeded to have unprotected sex a couple days after taking plan b. Will it still be effective after the fact? I also want to add that I did bleed on may 11th through the 13th. Does that mean the plan b worked? Anyone else take the morning after pill and bled but still ended up being pregnant?
