I’m all set to start my birth control as soon as I get my next period, then I’ll be starting medication to prepare for my retrieval in February. I never even imagined that cycles could get canceled until I saw some posts on this app! Now I’m so worried that my cycle could get canceled for some reason. I’m 36, and I’m curious about what could cause doctors to cancel your cycle? I feel like I’ve already waited long enough for a baby so I don’t know if I can emotionally handle more delays!
