Dear friend ...
Thanks for your query to Healthcare Magic
I read your concern and your symptoms are likely to be hormonal variation and not because of pregnancy
as stomach pain is not associated with vomiting
and other symptoms .
You can check Hcg level to confirm that your boyfriend doesnt made you pregnant this time .
If HCG is negative you can take Omeprazole
to relieve your symptoms .
Do not be worried ... You can ask me furthur if you have any queries .
