Pcos but regular periods !?!

Sheets • Ttc #1 3 years of marriage . Getting desperate ! But keeping the faith
Hello ladies !!!
I wanted your opinions on this : 
I have been told since I was a teen that I have pcos . They did ultrasound when I was 15 as I had bad acne and the whole shebang that comes along with pcos . No treatment was done as I didn't want to go on bcp. The acne eventually cleared up . But now that I'm ttc (I'm 30) I went and got another  usg and they detected cysts . My hormone tests were done and basically all were in normal range . Also , I get periods very regularly every month, though they range between 28-34 days . My gynaec said it shouldn't be problem in conceiving as my periods and hormones are regular . I'm <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> with opks and I'm Getting positives every month . But obviously I'm not pregnant . I'm so confused . Do I have pcos or not ?if yes , how am I so regular in AF ? How am I getting a clear pattern in opks every month? If I don't have pcos , why am I not getting pregnant ! Oh lord , being a lady is tough 😩
