Delayed cycle after egg retrieval

Hey!

I had my egg retrieval on January 17th and had my next period 15 days later. We met with our doctor last week to go over the genetic testing results and are all set for transfer on my next cycle! Because I’m incredibly impatient I started using the clearblue advanced opk to be able to pinpoint ovulation and start of my next cycle. I started testing on CD 9, got a flashy smile on CD 11, and had flashy smiles until CD18 with no peak, then ran out of tests. Glow predicted I would ovulate CD16 but I haven’t noticed any normal ovulation symptoms yet, and now for the past few days I’ve been having light brown/red discharge. Just looking for some insight-did anyone else experience this? If so, how delayed was your cycle? Thanks!!
