You can take a repeat urine test one week after the first one and better still, go for the blood test
as you are well overdue. Since you have irregular periods
, it is difficult to predict your ovulation time and hence the fertile period. You should consult a specialist to know the cause of your irregular cycles, have investigations like a complete hormonal
profile, thyroid profile, ovarian study and so on. You may use the ovulation kit to predict the ovulation time in the present state of menstruation
. Take care.
