There are several reasons for a person to not conceive. Few reasons for infertility are tubal blockage, hormonal imbalance, PCOS, decreased follicles, cervical factors etc.2) All these things cannot be detected by a pelvic ultrasound. Since you have small eggs, chances are high of you having hormonal imbalance. That has to be evaluated. You need to get your blood tests done like FSH, LH, AMH, testosterone, oestradiol, TSH, insulin etc.3) You might also need to get a tubal patency test like HSG done.4) If everything is normal, you might be asked to increase the dose of siphene or add injections.5) Do not lose hope, you will conceive with proper treatment.I hope this was helpful and I wish you best of luck.Regards,Dr. Shikha Shah </s>
