Discharge

[sam6386]

Ive posted on here a lot I know but I am scared...
So heres the story I went to my GYNO in the beginning of ( I believe it was the 4th of June)  to get a pap smear she told me recently she had checked for STDs (making it seem like she checked for all and that I was negative on them) A few days after that I had unprotected sex with my boyfriend once, and after that we have been having protected vaginal sex, and I will continue to do so. (Last time we had unprotected vaginal sex was June 11th) I have had UNPROTECTED ORAL sex most of the time giver (no ejaculation in mouth and once reciever)... A few days ago I ended up getting long stringy discharge from my vagina after a long walk and after I went to pee during the shower I was taking, this ended up coming out...I was really scared and worried but I could not call the GYNO because it was late at night and they were closed. The next morning I had a tiny bit on my underwear then it had stopped. I wiped down there kind of hard the next few days (to make sure I had gotten it all out) and it seemed to cause irritaion... not a lot just a little and after this Ive experianced clear discharge (like water, making my underwear wet and uncomfortable.) this has happened before to be but seems to be a little more then usual or making because I am noticing it more. I am also on Doxycycline for Lymes Disease which they/I believe I have. And have been on this for a little over 3 weeks...I have also had abnormal stools soft/then hard and had bleeding twice in the rectal area one right after another about 3 days ago...a few days after this stringy discharge occured. My rectum seems to be aggrivated too because I believe Ive been wiping hard also... I am so overwhelmed. Do you think this could be an STD or anything?
