Hello,
Thank you for your query at DoctorSpring.com
The symptoms are definitely not related to sex.
She might be suffering from a gastric infection, I will advise her a course of antibiotics like Ciprofloxacin 500 mg twice daily for 3 days, and Cap. Omeprazole 20 mg twice daily for the same duration.
Let me know if she is improving.
Hope this was helpful,
Regards.
Patient replied :
I have done sex with her as her periods were ending but spme blood was there she doesnt want to get pregnant kindly suggest me the medicine for that too
If you had sex on her periods, then she won't get pregnant.
Do not worry.
Regards.
