I had a dry humping episode 2 weeks back post which I got my periods for 3-4 days but with slightly lighter flow. I also got a urine pregnancy test done which is negative. However, i'm having a sharp pain in my pelvis ever since my periods ended and also in my lower back and lower abdomen. My legs and feet are also hurting. Please advice what can it be as the pain isn't constant although severe when it pains. I'm having a super sticky and slimey white vaginal discharge also. It's bothering and limiting my daily activities.
