Hi I been having pain close to my belly button, it comes here and there , idk what it can be. Back pain, naseous but it goes right away, I had my period last month on the 15th of April but before that week I has sex on the 11th of April but my period came and my bf didn t cum inside me and ever since then. haven t been sexually active. Idk what it could be. And I noticed my period didn t come on the 15th of may and I felt nauseous, but then it went away, so I took vit c and parsley to mske my period come and it came on the 3rd day.. So idk what I hav3. Could it be a stomach issue?
