Birth control and clear stretchy discharge

Hey so I need help! I have been on the birth control pill Lo Loestrin Fe for about 6 months now. My boyfriend and I had unprotected sex this weekend and I realized that I had stretchy clear discharge after we were done. He did not finish in me, but I am still stressing out. I don’t know much about that type of discharge on the pill, but I know that combination pills prevent ovulation and stuff. I have never missed a pill and I take it on time every single day. Please help. I just need reassurance that I am more than likely fine in this situation!!
