Hello
Since you are in physical relation and don't want
pregnancy .
Your doctor prescribed krimsom 35 i.e. cyproteone 35 for cyst .
Now you are having headache , nausea,
vomiting,
muscle pain , fever ,all these are most common side effect of this drug including mood changes .
Since just 14 days passed , so need not to worry , after 1-2 months this drug will adjust and you will not feel such symptoms , so take till this drug . But if symptoms are severe you may need drug like
pantoprazole -d one or two on empty stomach .
If still drug don't adjust , you can change this drug like other oral
contraceptive , that will also help in cyst ( femilon ,a birth control pill ) also.
Usually oral contraceptive are hormonal pills so that cysts can be taken care of as well as act as contraceptive.
Once , you stop the oral contraceptive pill , as long as as there are no medical concern you should not have any problem with future conception.
So consult your gynea and get his opinion.
Good luck.
