Cervical mucas

The birth control pill that I am on is supposed to stop ovulation and I take the pill perfectly every morning. I know that the pill also changes your cervical mucus. I check my cm everyday and since I’ve been on birth control I haven’t noticed the egcm that a person typically has when they are ovulating. Since I only have just the white sometimes cloudy cm does that mean I’m not ovulating? Or does that mean that my birth control has changed my cm and I could still ovulate and not know it. The reason that I am concerned is becuase I had sex on Wednesday which actually ended up being the last day of my period and I still had two more days of placebo pills. I changed the feature on my app to say I was on not type of birth control and when I did that it said I would be in my fertile window on Sunday (today). So on Friday, instead of taking my final pill I went ahead and started my new pack. Was there enough hormones in my last pack to keep me from ovulating this early and since I started my new pack a day early, am I still good. The reason i ask is because I feel like I have been having cm from my body but when I check, it feels a little wet, but there really isn’t anything. But when I check up inside my vagina, I do have a little bit of white cm. Am I in my fertile window? Or am I okay. I’ve been on birth control since last May and I take it perfectly
