Hi I recently had a failed ivf cycle. My cycle was cancelled after egg retrieval due to no fertilization. After stopping the meds I had the regular bleed my doctor told me about. Now on this following cycle I tested positive on an opk day 15. My period is now five days late and I have had cramping on and off for a week and a half. Is it normal for your period to be late after a failed ivf even if I ovulated normally?
