Took plan b and.....

It's been 3 to 4 days now and yesterday I just now started feeling nauseous and stomach cramps and acid reflux. Really bad cramping. Is that normal to feel the side effects? Now I was ovulating when I had took the pill . According to this app I was ovulating that is . Yall ladies prolly remember my other posts lol. But I saw the comments and alot of women seem to know alot about plan b .

Side note; I'm dying. Never taking the pill again. To not reccomend.
