question on "symptoms"

why is gassy not an option as a symptom? I get really gassy on my period.... I feel like gassy should be added to the list of symptoms .. also, I'm not trying to get pregnant but my form of birth control isn't listed, I have nexplanon, we use the pull put method but I am also on birth control but for an accurate post I usually just put "other" and even though I'm not trying to get pregnant I'd still like to be able to see when my fertile days are or would be... But because my profile says I'm not trying to get pregnant that option gets taken away which I don't feel is right. just because I'm not trying to have a baby doesn't automatically sterilize me... I'm still fertile. 😒
