 [ Symptoms ] i had a normal period about a week after intercourse then another a month later than 2 months later spotting problem  i am also feeling slightly nauseas i have not been sexually active after the first incident however i am mainly wondering what could have caused the spotting and if by seeing that i have stressed myself into making up the nausea and thinking it is worse than it really is [ Disease ] you need a diagnosis first not something that i can provide for you blindly over the internet unless the true nature of this hard lump is known and the reason for your night fevers they do not have to be related there is really no way for me or any medical professional for that matter to know if you need an antibiotic let alone a specific antibiotic without an examination your first and most important step is to be properly examined and diagnosed i would suggest that you not self treat this lump with clindamycin since this may interfere with a culture if your doctor feels this is needed
