Firstly, you should give yourself some time-like 6 months with continuous trial for natural pregnancy
without using any contraceptive
methods and timing the intercourse to around the fertile period around ovulation as your wife gets regular periods. If pregnancy dose not occur during such period, see an infertility
specialist for further assessment and support. Occasional delay in the periods is normal and can be due to stress, hormonal
disturbances and trauma. Take care.
