This is a good question.
If this is the single cyst n one ovary only and of the size you mentioned, it can not avoid as such from you getting pregnant unless it is a part of polycystic ovary syndrome.
If this is single, pregnancy is still possible.
But you have to see that all other parameters of you and your husband are normal.
If this is the simple cyst, this usually gets dissolved on its own.
Hope this helps you.
