breast sakit tapi upt -tive

hi period delay 2mnggu, upt pun still -tive..tapi breast teramat sakit dbhagian nipple..perut cramp on off..lpastu dulu sy cheese lover tp skrg sy rasa mcm geli nk mkn n rasa mual klu fikir psal cheese..adakah prubahan hormon juga jd mcm itu??? n masih dlm tanda hamil ke??
