adviceee please ?

iv been semi constipated lately and my stomach has been bloating so badly from it and iv been having the worst lower abdominal pains!!! any advice on how to help it go away? also a need a long term remedy besides lube itself and spit (tmi) for vaginal dryness that comes out of no where sometimes. iv taken zyrtec which is an allergy pill and it dried me up so badly down there. what are some over the counter things to help with that? I go to my gynecologist Tuesday so I'll also ask her. just seeking some woman to woman advice! :)))
