so i had unprotected sex yesterday and the 22nd. i took a plan b yesterday morning because i was feeling anxious but me and mt husband talked and we decided we want another baby) my period isn’t due until the 31st and i think i ovulated on or around the 16th. im having breast pain and cramps with some white discharge. i was wondering since i took the plan b a week before period and after i already ovulated for the month if the plan b wouldn’t work? i also had unprotected sex after i took the plan b because we decided we so want to conceive before my husband gets sterilized soon, so would me having sex the night i took the plan b make the plan b not effective? seeing how i kind of regret taking it because i really won’t have a chance to get pregnant ever again.and how long is the plan b supposed to stay in my system because i want to get pregnant now
