what’s going on?

So I had unprotected sex a day before my fertile window which still gives me a slim chance of getting pregnant.. maybe not so much but maybe I ovulated earlier this cycle then normal. At 6 or 7dpo my breast were EXTREMELY sore which I thought was way to early to be getting PMS symptoms considering the fact AF wasn’t due until a week and one day. I’ve had a few symptoms and one that really stuck out the most was my CM.. I had A LOT of white lotion like cm which I never really had before. I get it before AF but it was always creamy and medium like. It stuck out to me because it seemed different I never had so much. By now I should be around 9 to 10dpo and my breast aren’t extremely sore anymore. I’m getting CM but it’s not heavy as it was. Normally when I start AF I always get this feeling in my lower hip area and back and every time I feel that AF ALWAYS shows up. But it has happened to me twice and AF hasn’t showed up as it isn’t due until January 6th. I’m not sure what’s going on I feel like my body is giving off mixed signals. I’m not asking anyone to determine if I’m pregnant I just want to know what’s going on
