plan b side effects?

i took plan b after missing a few of my pills (stupid) and the condom breaking (stupid). i took it 48 hours later. this was three weeks ago.

i’ve been nauseous, crampy, headaches, dizzy, tired, very emotional and cranky, etc. im assuming that it’s because i have essentially two pill packs in my system that’s causing these symptoms. i just need reassurance that plan b can cause symptoms three weeks later and it’s not a baby 😂

i took one pregnancy test and it had a slight line but it was vvvf and it was a blue test. tried again with a dollar store test and it was negative. it is still early so i’ll test again in a week.

anyone else that has taken plan b experience this?
