Graphic Lady Bizness: I stopped taking birth control mid-pack in JULY and have only had 3 periods since. Normal?

I lost my birth control pills about two weeks into starting a new pack back in July while on vacation and didn’t bother refilling the prescription for several reasons.
I had been taking it before that for years, though there were the occasional months that I’d forget to take several in a row and just skip to the next pack.
I had a period a few weeks after that, one in November, and one in January. It’s mid-April now and I’ve been having mild cramps for about a month and somedays it feels like I can feel my right ovary being squeezed.
I never missed periods before that and chances of pregnancy are pretty slim.
What gives? Does it really take this long for my system to get back to normal? I’m seeing the gyno next week but wanted some feedback before then.
Thanks!
