I know you all must think im a paranoid freak

(due to my other posts about pregnancy)
but I just was curious as to whether or not bcp causes vaginal discharge? I know it thickens your cervical mucus which makes it harder for sperm to get through (ortho tri cyclen lo). Ive been on them for about 2 yrs. And in the past 8 months (since I started worrying about pregnancy), ive noticed whenever I wipe (sorry to be gross), I have this clear shiny discharge or sometimes light yellow globs (not everytime I wipe). There's been several times when it has come on to my underwear. However, this past week it has been worse (i actually feel wet at times), could it just be this menstrual cycle or the fact that I was on xanax xr for a month and then a week ago today started paxil cr, so there are a lot of changes going on in my body between the hormones in the bcp and whatever chemicals the paxil is releasing. I know I dont have any infections cuz ive been having abdominal pains and I have been seeing numerous drs. Since march all of which have taken urine samples and cultures, one just done a few weeks ago, which came back fine.
Any ideas?
