please help me ??

Hi everyone, so about two weeks ago I took a plan b for some stupid reasons but anyway. I have been experiencing some back pain, abdominal pain, nausea, hot flashes, constipation, headache, fatigue, and I have been really hungry but become really bloated. I was looking up some symptoms online and it says I could have indigestion?? So I’ve been taking some fiber pills and stuff but could this just be results of the plan b? I know I’m not pregnant cause I didn’t even have sex but anyway just please help me out !
