I have read your query I understand your concerns. Following is my reply: 1 The spotting could be one of the signs of ovulation or if she had ovulated and conceived, it could be an implantation bleeding due to implantation of embryo. 2 The ovulation could have been missed by ultrasound by mistake. Hence, I would suggest you go for other mode of ovulation testing like ovulation strips, serum LH levels along with ultrasound to predict accurate ovulation 3 try changing the brand and batch of Chat Doctor you have taken next time as some Chat Doctor in are defective. I hope I answered your query. I will be available for any followup queries you have. Chat Doctor.
