I have a horrible sinus infection and I had nausea the day after and cramps and really bad cramps after the morning after pill but is a sinus infection a sign of early early pregnancy please I’m freaking out!
Plan B is a huge dose of artificial hormone for your body to deal with. It's meant for total emergencies.
It's not as reliable as regular hormonal birth control, it's simply worth a try in an emergency.
It will often give you any hormonal symptoms that you'd get with a period or pregnancy, for example. They may be more intense.
Your menstrual cycle may be erratic for weeks or months.
Your sinus infection has nothing to do with pregnancy.
