Reposting... it's been almost 21 days sex I had sex and period is 4 days late I took two tests last week both were negative not sure if it was just too early and I should take another or stop stressing... I've just been feeling so sick 🤢

Original post:

I had unprotected sex around 10 days ago mid cycle, my periods are super irregular. I've had cramping and been so nauseas I can barely eat and every smell is making me want to vomit I bought 2 tests but not sure if it's too early.... my period should come by this weekend and today when I went pee I wiped and had light pink spotting...

Not sure when I can test, I'm really nervous any thoughts or suggestions?

I took a plan b 3 days (within the 72 hr period) I just feel so sick not sure what's going on
