I had sex without a condom on the 31st... I'm on the combination pill but lately I have been taking it 1-2 hours earlier/later and this morning I feel extremely sick, I have a sore throat diarrhea and vomiting I'm sooo scared now that I could be pregnant, I'm debating whether or not I should take plan b because it hasn't been 48 hours yet... do you think I could be pregnant and should I take the pill?
