Be seen today
These symptoms need prompt assessment even if you think the bleeding is a normal period.

Does any of this apply?
Book an appointment
Book a routine appointment if the pain regularly interrupts daily life, has become worse, or started after years of manageable periods.
You should also make an appointment for pain between periods, pain during sex, bowel or bladder symptoms, heavy or irregular bleeding, or symptoms that do not improve with appropriate self-care.
Every sign above is quoted from the sofidex article on Period pain. If you are not sure, err upward — it is always reasonable to be checked.
