Yesterday my man and I had sex for the first time in 2 weeks I included that info because I don’t know whether it would be useful right now but it was the first time he had finished inside me (I am on birth control). Today I’m having a loss on appetite and am running a slight fever. Can someone tell me why this is happening? Is it because he finished inside me or is it something else?

P.s. He has a cold and it was one day after my period ended
