Re: no idea whats going on!
IF I understand you correctly when You urinate you spot bleed. This is a sign of a UTI. Is there any burning when you urinate. Is there Pain? Is your urine cloudy or smell like sulfur?
If you are spotting through your vagina it could be a whole host of things.
Headaches and fatigue are really vague symptoms and could be due to stress. Also could be related.
And not sure at all what sex needing is? Unless you feel like You need sex more. In which case, If you are having a lot of sex with multiple or even 1 partner you should check for sure for UTI. Frequent sex without urniating before and after can cause chronic UTI Infections. If you haven't had your male partner(s) use the love glove then you probably should be tested for all STDs.
I wish I could offer you more and most importantly hope this helped
