you can not diagnose a cyst based on symptoms. i have multiple cysts on my ovaries and i had no idea until a full bodied mri was done for another reason. i had no pain, no changes in diet, nothing.
if it has been longer than 2 weeks take an hpt. talk to your parents and let them know you're sexually active and there is a possibility you're pregnant. IF you're not, then you need to get on some form of b/c asap and ALWAYS (i can't stress that enough) use condoms. b/c DOES and has failed. my brother got his 17 yr old ex g/f pregnant while she was on nuvaring. their baby is due in a few short weeks. he refused to use condoms and wouldn't listen to anyone thinking b/c was 100% effective. HE was a b/c baby.
i think you sud go TAKE A test and see if ur pregnant because these are the symptoms my frend had wen she got prego so go take a test and see wat happens
sometimes u could worry to much and u think theres something wrong wen there really isnt
