Thanks for your query. You wont get pregnancy
symptoms so fast, it takes time for after intercourse say 3-5 weeks to really get pregnancy symptoms. Your symptoms are more like GASTRO-ENTERITIS
. You might be ANXIOUS as well. I suggest you take some probiotic
drinks and lots of water.
I hope this information has been both informative and helpful for you. In case of any doubt, I will be available for follow ups.
Wish you good health.
