"i have used plan b so many times (which isn&#039;t good) but my doctor stopped prescribing me birth control due to a blood clot. but anyways i&#039;ve had unprotected sex with my so a few days ago and i took the pill a few hours later . immediately i got cramps and i never usually experience the symptoms ! i know i have nothing to worry about because plan b always had my back lol the most important thing is to never stress about anything plan b works!!!"
