mood swings ?

My bf wanted to have sex so I pleased him, but while he mas kissing me I didnt feel anything, while he stared it, I wasnt into it. For the record I am sick, I was feeling like shit and definetly not in the "mood". After we finished he stared to carrasing me, but I didnt like it. I always love enerything but this time I was mad at everything, including he kissing me. The I stared to cry, then I was fighting about some stupid shit and then I was LAUGING. Then got really mad again, like wth. Please tell me that was a mood swing...
