hi welcome to hcm.see if ur one tube is open then no need for hysterolaproscopy u may chose iui and may get success but yes if your both tube blocked then hysterolaproscopy is necessary to find the reason for blockage it may or may not real block sometimes because of spasm die can't pass.also make sure your husband semen analysis
is normal.and ur all hormonal
assay normal like FSH,LH,THYROID,PROLACTIN
plus your ovum size still smaller it should be 18mm at time of ovulation which may be increase through hormonal tab and injection.first avoid stress do regular exercise and yoga plus castor oil pack massage on your abdomen which also help in open the blockage.consult any infertility
specialist for ur trouble.if u overweighted then reuce ur weight ,plus take more fiberous diet reduce consumption of carbohydrate
because it ends in increase glucose level increase male hormone in u.
