### input:
my boyfriend and i had unprotected sex last wednesday afternoon around 1.  that night i went to dinner with my parents at souplantation and took my first pill of my fifth month of tri sprintec at 6pm. At 3am the next morning i woke up feeling nauseous and threw up a few times. I had diarrhea, sweating, and shaking/chills.  I thought it had to be food poisoning. The next few days I had been unusually gassy. But for the most part felt fine. Then last night, I ate rice with a lot of sliced garlic in it, and got really bad heartburn. I have acid reflux disease so ive had heartburn before, but never this bad. I couldnt sleep much due to the feeling that i would throw up. I got maybe four or five hours of sleep total. Today I also dont feel that great, but Ive also been thinking about the possibility of being pregnant. Ive been very thirsty, but still have a dry mouth when i drink.  I have diarrhea and occasionally constipation. I took a clear blue pregnancy test today and it came up negative however I am worried that it is not accurate because it is too soon. Could I be pregnant, or could I just be over thinking and worrying too much? Or is it possible to still have food poisoning, if thats what it was?

Hi, Thank you for choosing Chat Doctor. As you had unprotected sex, you should take emergency contraceptive pill like Plan B, rather than taking Tri-sprintec. Yes it is too early for a pregnancy test. I hope this information has been both informative and helpful for you. In case of any doubt, I will be available for follow-ups.
