I had unprotected sex three days ago, I took plan b 13hours after, been having weird feeling in my ovaries, super hungry, can never seem to feel full, really really tired, feeling weak, nausea and diarrhea. Is this just effects from the pills themselves or am i pregnant? I also took both at the same time not 12 hours apart like they say too. I've also been taking acetaminophen and ibuprofen for my headaches.
