How long after IVF did your cycle go back to normal?

Had a failed <a href="https://glowing.com/glow-fertility-program">IVF</a> cycle last month, which was devastating. Got my period, but now I’m on day 16 and still my OPKs say I’m not ovulating yet. Normally I ovulate on day 12 or 13. Is this normal? How long did it take your cycles to return to normal?
