Thanks for the query.
There could be some problem in follicular development may be hormonal
So you observe for few more days, possibly your follicle size will increase and you can plan unprotected intercourse
around the time of ovulation.
If not in the cycle you can go for ovulation inductions drugs. Possibly that can help in development of good sized follicle.
Then follicular stud can be done.
