Need answers!

I have wrote so many questions about this but so far I haven't got an answer! I'm 16 was on bc for 8 months but spilt up with my boyfriend and I'm young so not planning to get into any relationship soon. I wasn't sexually active but when on the pill Incase it did happen and I wanted to be prepared. So I come off the pill in February and straight away my periods were regulated I didn't miss a single period. I was late because my cycle went from 21 days to 28. Before I went on the pill I ovulated normally got all the right cm and it was clear my body was doing its job. But I'm now realising I haven't experienced no cm related to ovulating. I researched and found something called PCOS and it said you could have a normal cycle just not ovulate. Could this be the case? I'm clearly acared and want to find answers. I'm just so confused after 6 months of the pill why am I not ovulating like I was before I went on it? Please please please give me answers I'm only 16 and I'm so scared. Thank you
