Dryness

hi guys! I was wondering if anyone could provide any insight on this... I recently underwent surgery in my mouth (nothing too major) but was put on an oral antibiotic for 10 days, 3 times a day. i have noticed increased dryness, a very slight vaginal itch and I almost just feel uncomfortable. If anyone has experience with antibiotics, is this a normal temporary side effect? Or should I be concerned about a deeper cause? There are no bumps, rashes, or anything suspicious with the skin. Just a decrease in the amount of my normal discharge but other than that the discharge appears to look normal. It has more of a creamy texture. Let me know if anyone can help!
