Vaginal Dryness

I went and visited my boyfriend about three weeks ago, and since we are long distance we took advantage of the time we had and had tons of sex, we were safe too! I’m on the pill and we used condoms. The sex went smoothly. But ever since I got back home, I’ve been uncomfortable down there and my discharge has changed drastically. Usually I would get a good amount of discharge on the daily, but since then it has been little to no discharge and sometimes i smell down there. For a few days it seemed to be going back to normal, but then it went back to being dry and uncomfortable. I have started my period so I am not worried about pregnancy, I’m just concerned about my vaginas well being. Has this happened to anyone else? If so what did you do? Any advice helps! Thank you
