i have the same problem quite often. I know the treatment i got it in the past. I think that yrs was not foul, u better visit yr doctor..i am wondering how the pharmacist gave u the cream without a prescription.. anyway..usually it is candita, but it can also be caused byt bacteria, that's y u should first have micrological test of yr vagina fluids so u will have the right treatment. Secondly my doctor also gives me pills for the candita..a in-vaginal cream, an out-vaginal cream plus pills. it is also good to douche yr vagina before u will use the inside cream.
About yr bf don't be afraid, males got nothing..but maybe u can take it back from him, so he has to take some pills too..my doc alsways gives me pills for my bf..also the blood u saw i think it is from yr period..don't be scared, it is a routine infection.
Also about yr period..well u should continue it (medication).. don't feel secure just because after 2-3 days u r not itching.. must finish yr medicines. Once i had my period like that, i continued my treatment after it..and it worked..
Go to yr doc or call him and tell him what happened. Tell him also for yr boyfriend. In my country docs say that i can take it back from my bf..in italy they say no..in uk the same..what does yr doc say? I would like to inform me!
