Irregular period! Last period 53 days ago!

So i have been on birth control pills for 15 years, im 30 now, i recently came off the pill in july, i had my period july 18-21 then did not get my period until sept 7-12th thats 47 days, now its 53 days since my last period in September. Is this normal? I would like to try and conceive but I cannot figure out at this point when I’d be ovulating :(
