Ovulation mucus and testing

Hey guys I’m new to this & I hope this isn’t to weird to ask. I don’t have a GYNO appointment until February 13th and I’m actually going crazy! My mother had such a hard time getting pregnant & I’m so scared because I’m still younger like really younger & I’m not seeing any normal cervical mucus for ovulation.. I don’t see any egg white or milky white or stretchy clear mucus ever even when it says I’m in my fertile window on glow. I have never tried opk tests & I was wondering what everybody likes & best ones to get when I do try. If anybody knows of anything like the cervical mucus thing please let me know! I’m terrified to not be able to have kids. Me & my boyfriend don’t use condoms or anything & haven’t for probably almost a year now & I’m still not pregnant. I’m just wondering if anybody has had it where they have seen no cervical mucus at that time and still got pregnant or if they saw a doctor & this same thing was happening and they told you that it was all fine? Please help! I’m going crazy!
