My period is not back

Pamela

I have PCOS and I stopped taking birth control pills back in December 2018 to TTC and as soon as i stopped them i had a period but i guess they call it a hormonal period meaning not a real period .. and my last real period was December 22 and since then my period hasn’t come back. Pregnancy tests read NEGATIVE and i don’t know if it’s normal for my period not to regulate by now. Any suggestions??
