hi destiny,first of all thank you for asking this question on this forum. Bicornuate uterus is a condition where uterine cavity is divided into two parts.you have already said that you have undergone three misscarraiges, possibility of having small cavity could be there.To prevent further stress,i would advice you to straight away go for hysteroscopy (visualizing uterine cavity through scope passed via vagina)by a trained gynaec endoscopist,look for the space inside uterus, if the space is adequate,you can conceive and can continue pregnancy till term by having good progestrone support.If cavity seems to be small, metroplasty operation can be performed.In any of the case you can become pregnant.Be optimistic.
