Plan B side effects ? Comment

Disclaimer : I have no shame in posting this, it was sex with my boyfriend of 2.5 years... I just hate the stigma around the pill... anyways, I’m currently 4 DPO (not confirmed) I took the plan b 2 days ago. I am not feeling well at all. Today I was having light cramps but when I got them it made me feel like I wanted to throw up. Just constant nausea today. I’ve had a ton of CM. Mainly EWCM mixed with creamy. I usually barely have any. What’s your experience ?? Did you get pregnant even though you took the plan b?
