I have a few questions.

Alright, this might be a little TMI but what on this page isn't really? Lol.
So on Thursday my boyfriend and I had intercourse and of course he came inside of me. However, I am supposedly on my 'ovulation' period as of Friday. Since intercourse I have had no cervical mucus. I have tests upon test done before this happening (I have some underlying issues with my kidneys and recently noticed my right ovary was enlarged so my doctor did a complete work-up with ultrasound and transvaginal and all came back great). So, with that said, I have no abnormalities going on. However, I have been extremely hungry. I feel like I can eat, and it's not enough along with increased urination and some headaches here and there. I figured it would be wayyy to early to have symptoms of pregnancy, however, my boyfriend and I have had sex other times this month.
What I'm really trying to ask though is that has anyone experienced NO CM after sex for a couple days? Is this normal? Or could I be pregnant? I've always thought that pregnany caused more mucus if anything.
Also, I did have a miscarriage back in August. I have had no birth control and my period was wayyyy late. And by late I mean I was suppose to get my period on October 29th and it didn't come until I was 9 days late (November 7). I wish I paid more attention to my CM when I was pregnant so maybe I could have answered this question myself, but it was a shock and surprise and didn't think about it. 
Thank you for any insights y'all can give me. I searched forever on google and figured this was the best place to try instead.
