Not sure what to think?

Lately I’ve been feeling kinda crappy thinking I’m sick or getting sick.. I’ve had this metal taste in my throat for a couple days and it’s bothering me. I’ve noticed fatigue my boobs and back. I have been working a lot also. I’ve been having nightmares and can’t sleep as good. Super nauseous..My vagina hurts feels sore and I feel like my sex drive is not as high as normal. What do you think is going on I just ended my period like 5 days ago. And me and my boyfriend have sex a lot but we always use a condom?
