Sorry too Oriana x
Mrs, are you using OPKs? I think cm usually happens a day or 2 before ovulation but I don't usually get much. I would def check with your clinic to get their advice. I believe ultrasound scans are safe and are in no way harmful to an egg or embryo.
Nothing new my end, I'm on 13dpo which is unheard of for me so even though BFN at least the cyclogest has really improved my luteal phase and I feel I'm at least on a level playing field now.
