Hello.Thanks for choosing HealthcareMagic forum.
A small cyst in the ovary may be a developing follicle which releases the egg or may be a functional cyst or may be a benign cyst
. If your periods are regular then there is nothing to worry. It will not hinder in your pregnancy
.It will disappear after 1 or 2 periods.
Hope I have answered your query. I will be available if you have any further queries.
