Does any of this apply?
Book an appointment
Arrange a routine fertility assessment if pregnancy has not occurred after 12 months of regular unprotected sex.
Consider seeking help after six months if the partner who would carry the pregnancy is 35 or older.
They are not routine features of infertility.
The article also says
Seek earlier assessment if either partner has a known concern, such as absent periods, previous pelvic infection, endometriosis, testicular problems, sexual difficulties, cancer treatment, or a history of surgery involving reproductive organs.
Every sign above is quoted from the sofidex article on Infertility. If you are not sure, err upward — it is always reasonable to be checked.
