I attempted IVF in March (not my first cycle). We are paying $$$$ so I decided it was too much money for such low odds with only three growing follicles so I cancelled at day 8 and stopped all drugs. My period arrived at CD19. The next cycle I had a blood test at CD 17 which showed I ovulated so I thought I was back to normal but then my cycle was only 19 days long? Has anyone else had irregular cycles after IVF, particularly if you took Synarel? I know our cycles shorten as we head towards menopause and am paranoid about this, so just hoping others have had the same experience.
