Craving ... already!?

Ok I'm around 9dpo. And I'm literally craving cans of pop in almost cryed today because I could get hold of one! Would that even be possible so soon??... I know on craved pickles before my period with my last baby... iv also had really bad headache for two days light cramps my cervix is still high and soft and iv been Dizzy all and nauseous all day... also really tired.... only just realised how many symptoms I have from writing that lol my boyfriend keeps telling me I'm pregnant but I'm trying to not get my hopes up as we only had unprotected sex twice. Once on cd 10 (I had ewcm with blood) and then again on cd 16. I have a 28 day cycle and due on in 8 days ... sorry for the long post just needed to get that off my chest 😃
