Too early to test

Ok so I stopped coming on here for a while cuz I just convinced myself I was pregnant all the time. Now I really think I am and know I'm gonna be gutted if not lol. Not due til next wed but my tummy feels 'different' I'm so emotional more than when af if due. Really spotty. Headaches more than usual. No sex drive whatsoever (which is really strange) and my cervix is so tight and closed when we did BD last night it hurt :( I don't know if it's all in my head I have no idea. Any of you ladies experienced any if this? It's the cervix thing really!! Xx
